Do you have any idea about this problem?
Question:
Write and execute an LC-3 assembly program which concatenates two strings. The first string begins at memory address x4000, and the second string begins at memory address x5000. Strings always terminate with a 0.
Example:Before your program executes:
M[x4000] = 5 M[x5000] = 6
M[x4001] = 2 M[x5001] = 1
M[x4002] = 8 M[x5002] = 8
M[x4003] = 4 M[x5003] = 0
M[x4004] = 0
After your program executes:
M[x4000] = 5 M[x5000] = 6
M[x4001] = 2 M[x5001] = 1
M[x4002] = 8 M[x5002] = 8
M[x4003] = 4 M[x5003] = 0
M[x4004] = 6 M[x4005] = 1
M[x4006] = 8 M[x4007] = 0
Here's an idea: write a loop to locate the address of the first zero word starting from 0x4000. Once you've found that, write another loop that will copy words from 0x5000 and further to that address, terminating once the zero byte is copied.

I would like to know is there any way to set Header with 60 char in SALV? Since there is a CHAR limit of 40 when I try using SET_LONG_TEXT method. I am using this SALV to both display and download it as an excel too.
My Prod Code looks like this below.

Also, I am using the same piece of code to display the SALV where header gets truncated to 40 char.
I'm creating an app in App Designer. What I would like to do is when selecting one or multiple options, these get assigned a value of 1.
The list(i.e. "Column") is read in the following way and list options are assigned to a struct variable with a default value of 0.
table1 = readtable("file.xls");
for i = 1:length(rmmissing(table1{:,"Column"}))
s.(char(rmmissing(table1{i,"Column"}))) = 0;
end
This outputs the following table.
s.Anna = 0
s.Bett = 0
s.Cyrielle = 0
s.Dylan = 0
My problem is that I can't figure out a way of updating the value from 0 to 1, whenever I highlight one of the options. I don't know how to essentially pick up a selected value and updating it.
So as an example, If I highlight "Anna" and "Cyrielle", these should update to 1, as shown below.
s.Anna = 1
s.Bett = 0
s.Cyrielle = 1
s.Dylan = 0
I tried an if statement like. Whilst this works, it means I have to hard-code the names, which I don't want. So it needs to dynamically pick out the name that is selected.
if app.ColumnListBox.Value == "Anna"
s.Anna = 1;
else
s.Anna = 0;
end
The listbox would look like this:
Listbox
The output I get when selecting one name is:
s =
struct with fields:
Anna: 1
Bett: 0
Cyrielle: 0
Dylan: 0
However if I select multiple options, everything goes to 0:
Multiple names
s =
struct with fields:
Anna: 0
Bett: 0
Cyrielle: 0
Dylan: 0
The code now is as follows:
names = fieldnames(s);
for j = 1:numel(names)
name = names{j};
if app.ListBox.Value == string(name)
s.(name) = 1;
else
s.(name) = 0;
end
end
assignin("base","s",s)
Any help would be much appreciated!
You should be able to make your if condition less hard coded with something like
names = fieldnames(s);
for iField = 1:numel(names)
% Assign current name to variable, e.g. "Anna"
name = names{iField};
% loop over the fields and check if selected
if app.ColumnListBox.Value == string(name)
s.(name) = 1;
else
s.(name) = 0;
end
I have a while loop that calls on a function (def update(i)) and performs the calculation for the required number of times (until the while loop condition is no longer met) in Python3. What I now want to do is put different values of 'i' through the while loop and therefore through the equation 'dv' (shown below). So when the while loop ends I need the whole process to repeat with the next 'i' value. All the i values are in an np.arange array called 'i_es'. I have tried to implement this with the while loop nested inside a for loop as shown below...
import numpy as np
def update(i) :
dv = (e_l - v_s[-1] + i*r_m)/tau_m
v_s.append(v_s[-1] + (dv*dt))
return is_spiked()
def is_spiked() :
if v_s[-1] > v_th:
v_s[-1] = v_r
return True
return False
r_m = 10
tau_m = 10
v_th = -40
e_l = -70
v_r = -70
v_s = [v_r]
spike_count = 0
t = 0
t_total = 1000
dt = 1
i_e_start = 4
i_e_step = 0.1
i_e_final = 5
i_es = np.arange(i_e_start,i_e_final+i_e_step,i_e_step)
for i in i_es :
while t < t_total :
if update(i) :
spike_count += 1
t += dt
print ("Current = ",+ i, " Spike count = ", + spike_count)
However, when I run this I get the following output:
Current = 4.0 Spike count = 71
Current = 4.1 Spike count = 71
Current = 4.2 Spike count = 71
Current = 4.3 Spike count = 71
Current = 4.4 Spike count = 71
Current = 4.5 Spike count = 71
Current = 4.6 Spike count = 71
Current = 4.7 Spike count = 71
Current = 4.8 Spike count = 71
Current = 4.9 Spike count = 71
Current = 5.0 Spike count = 71
I can see that the current ('i') values are increasing as they should each time but the spike count is not changing.. The answer is always from the first value ('i' = 4) run through the loop.
Can anyone help with this?
Thanks in advance.
I would like to read my measurement data from a text file. The data have e.g. following form:
0 0.0531139
0.000157095 0.306123
0.000314191 0.133868

0.00125676 0.49554
0.00141386 0.433729
My code is as follows:
SUBROUTINE test(name)
implicit none
character :: name*(*)
real*8,allocatable, dimension(:,:) :: measMatrix
integer :: i,
& nrcols
nrcols = 2
nrrows = 10
allocate(measMatrix(nrcols,nrrows))
open(unit = 20, file = Dateiname, status = 'old', action = 'read')
do i = 1, nrrows
read(20,*) measMatrix(i,1:nrcols)
end do
close(20)
open(unit = 10, file = 'Test4.txt')
do i = 1,nrrows
write(10,777) (measMatrix(i,j), j = 1,nrcols)
end do
close(10)
777 format(F12.9,4X,F12.9)
deallocate(measMatrix)
END
However, the output is wrong:
0.000000000 0.000314191
0.000157095 0.000471286
0.000314191 0.000628381

0.001256760 0.495540000
0.001413860 0.433729000
What am I doing wrong ? :(
Thanks in advance for the help.
The first dimension is the fasted changing one, and the one contiguous in memory.
So in memory space your (10,2) is laid out as:
1 11
2 12
3 13
4 14
5 15
6 16
7 17
8 18
9 19
10 20
Maybe you want this:
nrrows = 10
nrcols = 2
allocate(measMatrix(10,2))
do i = 1, nrrows
read(20,*) measMatrix(i,:)
end do
...
do i = 1, nrrows
write(10,777) measMatrix(i,:)
end do
I prefer this:
integer :: Crnt_Row, Crnt_Col
nrrows = 10
nrcols = 2
allocate(measMatrix(10,2))
WRITE(*,*)'Shape(measMatrix)=',SHAPE(measMatrix)
do CurrRow = 1, nrrows
read(20,*) measMatrix(CurrRow,:)
end do
...
do CurrRow = 1, nrrows
write(10,777) measMatrix(CurrRow,:)
end do
Using IMPLICIT NONE will also help along the lines of what #d_1999 mentioned.
I am trying to figure out a way to make a for loop in which I can compare two cells that will give me two different means. One for class char and the other for class double.
This is what I have so far.
V = {2; 'tree'; 3; 'hope'};
W = {2; 'tree'; 3; 'hope'};
for i = 1:length(V);
if isequal(class(V{i}), 'double')
num = V{i}
elseif isequal(class(V{i}), 'char')
str = V{i}
end
end
for i = 1:length(W);
if isequal(class(W{i}), 'double')
acc_n(i) = isequal(V{i}, W{i})
elseif isequal(class(W{i}), 'char')
acc_s(i) = strcmp(V{i}, W{i})
end
end
mean_d = mean(acc_n)
mean_s = mean(acc_s)
The output I get is:
acc_n =
1 0 1
acc_s =
0 1 0 1
mean_d =
0.6667
mean_s =
0.5000
The output I want is:
1 1 for string, mean = 1. 1 1 for double, mean = 1
How can I do a loop where it only takes the numbers of the cell and the words of the cell separately?
Is there any possible way to only loop through the words or the numbers?
You can first extract strings and doubles and treat them separately, that will avoid loops.
V = {2; 'tree'; 3; 'hope'};
W = {2; 'tree'; 3; 'hope'};
VChar=V(cellfun(#ischar,V));
WChar=W(cellfun(#ischar,W));
acc_s=VChar==WChar;
VNum=cell2mat(V(cellfun(#isnumeric,V)));
WNum=cell2mat(W(cellfun(#isnumeric,W)));
acc_n=VNum==WNum;
Loop version: I haven't tested this but it should work.
%Assumes V and W have equal number of elements.
acc_n=[];
acc_s=[];
for i=1:numel(V)
if isequal(class(V{i}), 'double') && isequal(V{i},W{i})
acc_n=[acc_n true];
elseif isequal(class(V{i}), 'char') && strcmp(V{i},W{i})
acc_s=[acc_s true];
end
end
