What I want to do is trying to get different values of p_y_given_x for different sigma2_n separately in each line? When I use append it gives me result in one array. But I want separate results for each 0.2 for p_y_given_x.
Is there any hint for me?
for sigma2_n in np.arange(0.2,0.9):
p_y_given_x= np.exp(-(y_new-alphabet[t])**2/2/sigma2_N)
the result should be like this
p_y_given_x1=
p_y_given_x2=
p_y_given_x3=
....
ummmmm.... actually maybe this helps f(x)=x+2, f(1)=1+2, f(2)=2+2 and etc, I want to use a for loop and define x inside it and for each iteration use one values of x and insert it inside the function and calculate the f(x), but i would like to get values of f(x) separately and compare them, for example like this:
f(1)
f(2)
f(3)(separately in different lines)
not like this in one array[f(1),f(2),f(3)] for the last case we can use append()
In BASH
I run the following one liner to get an individual column/field after splitting on a given character (one can use AWK as well if they want to split on more than one char i.e. on a word in any order, ok).
#This will give me first column i.e. 'lori' i.e. first column/field/value after splitting the line / string on a character '-' here
echo "lori-chuck-shenzi" | cut -d'-' -f1
# This will give me 'chuck'
echo "lori-chuck-shenzi" | cut -d'-' -f2
# This will give me 'shenzi'
echo "lori-chuck-shenzi" | cut -d'-' -f3
# This will give me 'chuck-shenzi' i.e. all columns after 2nd and onwards.
echo "lori-chuck-shenzi" | cut -d'-' -f2-
Notice the last command above, How can I do the same last cut command shit in Groovy?
For ex: if the contents are in a file and they look like:
1 - a
2 - b
3 - c
4 - d
5 - e
6 - lori-chuck shenzi
7 - columnValue1-columnValue2-columnValue3-ColumnValue4
I tried the following Groovy code, but it's not giving me lori-chuck shenzi (i.e. after ignoring the 6th bullet and first occurence of the -, I want my output to be lori-chuck shenzi and the following script is returning me just lori (which is givning me the correct output as my index is [1] in the following code, so I know that).
def file = "/path/to/my/file.txt"
File textfile= new File(file)
//now read each line from the file (using the file handle we created above)
textfile.eachLine { line ->
//list.add(line.split('-')[1])
println "Bullet entry full value is: " + line.split('-')[1]
}
// return list
Also, is there an easy way for the last line in the file above, if I can use Groovy code to change the order of the columns after they are split i.e. reverse the order like we do in Python [1:], [:1], [:-1] etc.. or in some fashion
I don't like this solution but I did this to get it working. After getting index values from [1..-1 (i.e. from 1st index, excluding the 0th index which is the left hand side of first occurrence of - character), I had to remove the [ and ] (LIST) using join(',') and then replacing any , with a - to get the final result what I was looking for.
list.add(line.split('-')[1..-1].join(',').replaceAll(',','-'))
I would still like to know what's a better solution and how can this work when we talk about cherry picking individual columns + in a given order (instead of me writing various Groovy statements to pick individual elements from the string/list per statement).
If I'm understanding your question correctly, what you want is:
line.split('-')[1..-1]
This will give you from position 1 to the last. You can do -2 (next to last) and so on, but just be aware that you can get an ArrayIndexOutOfBoundsException moving backwards too, if you go past the beginning of your array!
-- Original answer is above this line --
Adding to my answer, since comments don't allow code formatting. If all you want is to pick specific columns, and you want a string in the end, you could do something like:
def resultList = line.split('-')
def resultString = "${resultList[1]}-${resultList[2]} ${resultList[3]}"
and pick whatever columns you want that way. I thought you were looking for a more generic solution, but if not, specific columns are easy!
If you want the first value, a dash, then the rest joined by spaces, just use:
"${resultList[1]}-${resultList[2..-1].join(" ")}"
I don't know how to give you specific answers for every combination you might want, but basically once you have your values in a list, you can manipulate that however you want, and turn the results back into a string with GStrings or with .join(...).
I am importing text values into a transformation using a Fixed Width input step. Everything is coming in as a string. I want to convert some of the string values to integers with a decimal point at a specified spot. Here are some examples of the before (left hand side) and expected results (right hand side):
00289 --> 0028.9
01109 --> 0110.9
003201 --> 0032.01
I've tried numerous combinations of the Format mask in a Select Values step (meta data tab) but I can't get the values I'm looking for.
Can you anyone tell me what combination I can try for* Type/Length/Precision/Format/Encoding/Decimal/Group* attributes for these fields to get the desired output?
Have you tried another step the reach your goal? You can try to use e.g. User Defined Java Expression setting it in this way:
Java expression: new java.math.BigDecimal(text.substring(0,4) + "." + text.substring(4,text.length()))
Value type: BigNumber
But this will convert your input to:
00289 --> 28.9
01109 --> 110.9
003201 --> 32.01
Because its output is BigNumber format. BigNumber or Number format can be used for decimal numbers. You cannot use Integer for decimals because it has no decimal part.
If you want a String output leave out the new java.math.BigDecimal() part from the expression above and set Value type to String. It will produce these results:
00289 --> 0028.9
01109 --> 0110.9
003201 --> 0032.01
This is the one suggestion. Of course there are another ways of how to reach your goal.
Is there a way for Gnuplot to read and recognize structured strings? Specifically, I have a few hundred files, all containing measurement data, with measurement conditions defined in the filename.
My files look something like "100d5mK2d0T.txt", which would mean that this data was acquired at 100.5mK temperature and 2.0T magnetic field.
Any chance I could extract the temperature and field strength data from the name, and use them as labels in the plot?
Thanks in advance.
With gnuplot's internal string processing you could come up with a solution (using substr and strstrt), but thats quite verbose.
Its better to use an external tool for the string processing, like perl:
filename = '100d5mK2d0T.txt'
str = system('echo "'.filename. '" | perl -pe ''s/(\d+)d(\d+)mK(\d+)d(\d+)T.txt/\1.\2 \3.\4/'' ')
temperature = word(str, 1)
magnetic_field = word(str, 2)
set label at graph 0.1,0.9 "Temperature: ".temperature." mK"
set label at graph 0.1,0.8 "Magnetic field: ".magnetic_field." T"
I am tring to plot a map with d3.js using GeoJSON, but the paths generated look like this:
<path d="MNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNZ">
the code and data are in this Gist:
https://gist.github.com/4157853
I can load the data just fine on QGIS.
Does any one know what is causing this?
The way you have specified the offset in the Mercator projection doesn't seem right. The projection.translate method expects a two element array:
https://github.com/mbostock/d3/wiki/Geo-Projections#wiki-mercator_translate
So instead of:
proj.translate(-43.8,-23.2).scale(10);
you would need to say:
proj.translate([-43.8,-23.2]).scale(10);
-- edit --
See source of projection.translate: https://github.com/mbostock/d3/blob/3.0/src/geo/projection.js#L139
projection.translate = function(_) {
if (!arguments.length) return [x, y];
x = +_[0];
y = +_[1];
return reset();
};
If the argument _ is not an array then +_[0] will return a NaN and therefore the x and y will become NaNs. (This is because trying to get one element from a number (e.g. 213[0]) returns undefined and casting undefined to a number (e.g. +undefined) yields NaN.)
If the code you posted in the gist is everything you're trying to run, then the data you show in data.json is not being loaded anywhere. Anyway, your draw function is acting on the data defined by the variable map (line 16), which refers to a simulation variable which isn't set anywhere. And even if it did, line 34 then refers to a features property of the object passed in as json, which map does not have.
In summary, you need to pass the JSON you posted in the gist to your draw function. Then it might well work. If you don't pass in valid data to the d3 SVG helpers, you'll get a bunch of NaN out.
