merging two string variables results in empty value - string

I'd like to merge two string variables (STRING_VAR1 and STRING_VAR2) into one string variable STRING_ALL, such that the content of STRING_VAR1 or STRING_VAR2 is copied into STRING_ALL depending on which of those two variables contain any data (see example_dataset). If both variables STRING_VAR1 and STRING_VAR2 contain missing cases, STRING_ALL should be missing as well.
I've tried CONCAT (see code below) but that doesn't work for some reason and leaves me with only empty cases for STRING_ALL.
STRING STRING_ALL(A4)
COMPUTE STRING_ALL = CONCAT(STRING_VAR1, STRING_VAR2)
Thanks in advance!

Eli's suggestion gave you the necessary information to solve this specific issue. If you want to know why, check the Command Order topic in the SPSS Statistics Command Syntax Reference. It discusses the different types of commands and the fact that some of them, such as COMPUTE, do not take effect immediately, but are stored pending execution of a command that causes a data pass.

JMeter functions and variables

I'm new to JMeter so this question may sound absolutely dumb...
I have a loop in which a variable (let's say it is called "raw") is being changed and written to file every iteration. The variable contains HTML encoded text so it has to be converted into plain text. I found out this can be done using __unescapeHtml function. When I tried using it worked but I ended up always receiving the same text as on the first iteration. Then I learned that I have to use vars.get instead of ${} to access a variable. So I changed ${__unescapeHtml("${raw}")} to ${__unescapeHtml(vars.get("raw")} which kind of helped: vars.get is getting the new value of raw each iteration but __unescapeHtml didn't work at all now - it just returns the encoded text from raw. I didn't succeded finding anything about this exact problem so I'm kind of stuck.
Ended up using
import org.apache.commons.lang3.StringEscapeUtils
...
StringEscapeUtils.unescapeHtml4(vars.get("raw"))
Don't know if it is a good way to do this but at least it works.
I assume, that you are using the expression ${...} inside a JSR-223 sampler or similar context. The user manual for JSR-223 Sampler states, that those scripts can be cached by JMeter. That is why you only get the values from the first time the context gets created.
The same is true for simple variable evaluations as ${varname}, as for function calls like ${__unescapeHtml(...)}.
The solution here is:
don't use ${...} inside of JSR-223 contexts, that might be cached.
you can however pass those expressions (${...}) into the context by using them as parameters through the input labeled Parameters on the JSR-223 Sampler – again assuming, that you are using it.
you can use the features, that your chosen JSR-223 context gives you, as you have done, by using the StringEscapeUtils#unescapeHtml4

Is it possible to split array in Gherkin to the next line

I have step where I am have String Array, something like this:
Then Drop-dow patient_breed contains ['Breed1', 'Breed2',.... Breed20']
I need to split this text on two lines. I know that in Gherkin there is expression """. I try something like this:
Then Drop-dow patient_breed contains ['Breed1',
"""
'Breed2',.... Breed20']
"""
It didn't help. Is there any solution?
What do you gain by putting this string in your scenario. IMO all you are doing is making the scenario harder to read!
What do you lose by putting this string in your scenario?
Well first of all you now have to have at least two things the determine the exact contents of the string, the thing in the application that creates it and the hardcoded string in your scenario. So you are repeating yourself.
In addition you've increased the cost of change. Lets say we want our strings to change from 'Breedx' to 'Breed: x'. Now you have to change every scenario that looks at the drop down. This will take much much longer than changing the code.
So what can you do instead?
Change your scenario step so that it becomes Then I should see the patient breeds and delegate the HOW of the presentation of the breeds and even the sort of control that the breeds are presented in to something that is outside of Cucumber e.g. a helper method called by a step definition, or perhaps even something in your codebase.
Try with a datatable approach. You will have to add a DataTable argument in the stepdefinition.
Then Drop-dow patient_breed contains
'Breed1'
'Breed2'
...
...
...
'Breed20']
For a multiline approach try the below. In this you will have to add a String argument to the stepdefinition.
Then Drop-dow patient_breed contains
"""
['Breed1','Breed2',.... Breed20']
"""
I would read the entire string and then split it using Java after it has been passed into the step. In order to keep my step as a one or two liner, I would use a helper method that I implemented myself.

MATLAB selecting items considering the end of their name

I have to extract the onset times for a fMRI experiment. I have a nested output called "ResOut", which contains different matrices. One of these is called "cond", and I need the 4th element of it [1,2,3,4]. But I need to know its onset time just when the items in "pict" matrix (inside ResOut file) have a name that ends with "*v.JPG".
Here's the part of the code that I wrote (but it's not working):
for i=1:length(ResOut);
if ResOut(i).cond(4)==1 && ResOut(i).pict== endsWith(*"v.JPG")
What's wrong? Can you halp me to fix it out?
Thank you in advance,
Adriano
It's generally helpful to start with unfamiliar functions by reading their documentation to understand what inputs they are expecting. Per the documentation for endsWith, it expects two inputs: the input text and the pattern to match. In your example, you are only passing it one (incorrectly formatted) string input, so it's going to error out.
To fix this, call the function properly. For example:
filepath = ["./Some Path/mazeltov.jpg"; "~/Some Path/myfile.jpg"];
test = endsWith(filepath, 'v.jpg')
Returns:
test =
2×1 logical array
1
0
Or, more specifically to your code snippet:
endsWith(ResOut(i).pict, 'v.JPG')
Note that there is an optional third input, 'IgnoreCase', which you can pass as a boolean true/false to control whether or not the matching ignores case.

How to save strings in matrixes in matlab

I want to have a matrix/cell, that has strings inside that I can access and use later as strings.
For instance, I have one variable (MyVar) and one cell (site) with names inside:
MyVar=-9999;
site={'New_York'; 'Lisbon'; 'Sydney'};
Then I want to do something like:
SitePosition=strcat(site{1},'_101'}
and then do this
save(sprintf('SitePosition%d',MyVar),);
This doesn't work at all! Is there a way to have strings in a matrix and access them in order to keep working with them if they were a string?
This:
MyVar=-9999; site={'New_York'; 'Lisbon'; 'Sydney'};
SitePosition = strcat(site{1},'_101');
save(sprintf('SitePosition%d',MyVar));
Works fine and yields SitePosition-9999.mat, note the syntax changes in lines 2 and 3.
Is there something else you're expecting?
EDIT: Based on your comment
Check out the documentation for save regarding saving specific variables
New example:
MyVar=-9999;
site={'New_York'; 'Lisbon'; 'Sydney'};
SitePosition = strcat(site{1},'_101');
save(SitePosition,'MyVar');
Creates New_York_101.mat with only the variable MyVar in it.

How to number floats in LaTeX consistently?

I have a LaTeX document where I'd like the numbering of floats (tables and figures) to be in one numeric sequence from 1 to x rather than two sequences according to their type. I'm not using lists of figures or tables either and do not need to.
My documentclass is report and typically my floats have captions like this:
\caption{Breakdown of visualisations created.}
\label{tab:Visualisation_By_Types}
A quick way to do it is to put \addtocounter{table}{1} after each figure, and \addtocounter{figure}{1} after each table.
It's not pretty, and on a longer document you'd probably want to either include that in your style sheet or template, or go with cristobalito's solution of linking the counters.
The differences between the figure and table environments are very minor -- little more than them using different counters, and being maintained in separate sequences.
That is, there's nothing stopping you putting your {tabular} environments in a {figure}, or your graphics in a {table}, which would mean that they'd end up in the same sequence. The problem with this case (as Joseph Wright notes) is that you'd have to adjust the \caption, so that doesn't work perfectly.
Try the following, in the preamble:
\makeatletter
\newcounter{unisequence}
\def\ucaption{%
\ifx\#captype\#undefined
\#latex#error{\noexpand\ucaption outside float}\#ehd
\expandafter\#gobble
\else
\refstepcounter{unisequence}% <-- the only change from default \caption
\expandafter\#firstofone
\fi
{\#dblarg{\#caption\#captype}}%
}
\def\thetable{\#arabic\c#unisequence}
\def\thefigure{\#arabic\c#unisequence}
\makeatother
Then use \ucaption in your tables and figures, instead of \caption (change the name ad lib). If you want to use this same sequence in other environments (say, listings?), then define \the<foo> the same way.
My earlier attempt at this is in fact completely broken, as the OP spotted: the getting-the-lof-wrong is, instead of being trivial and only fiddly to fix, absolutely fundamental (ho, hum).
(For the afficionados, it comes about because \advance commands are processed in TeX's gut, but the content of the .lof, .lot, and .aux files is fixed in TeX's mouth, at expansion time, thus what was written to the files was whatever random value \#tempcnta had at the point \caption was called, ignoring the \advance calculations, which were then dutifully written to the file, and then ignored. Doh: how long have I know this but never internalised it!?)
Dutiful retention of earlier attempt (on the grounds that it may be instructively wrong):
No problem: try putting the following in the preamble:
\makeatletter
\def\tableandfigurenum{\#tempcnta=0
\advance\#tempcnta\c#figure
\advance\#tempcnta\c#table
\#arabic\#tempcnta}
\let\thetable\tableandfigurenum
\let\thefigure\tableandfigurenum
\makeatother
...and then use the {table} and {figure} environments as normal. The captions will have the correct 'Table/Figure' text, but they'll share a single numbering sequence.
Note that this example gets the numbers wrong in the listoffigures/listoftables, but (a) you say you don't care about that, (b) it's fixable, though probably mildly fiddly, and (c) life is hard!
I can't remember the syntax, but you're essentially looking for counters. Have a look here, under the custom floats section. Assign the counters for both tables and figures to the same thing and it should work.
I'd just use one type of float (let's say 'figure'), then use the caption package to remove the automatically added "Figure" text from the caption and deal with it by hand.
