I need to apply a single integer across a group of cells in a matrix. I honestly have no idea how to do this. Here's the code that im working with right now
x = [0:0.1:3];
y = [-2:0.13:2];
for (x = 1:31)
for (y = 1:31)
end
end
But that and several other variations i've tried are not working whatsover.
The Integer "Load" needs to be inserted into all values of x where y = 0.
How can I do this?

@DEEPAK Chekuri: that is not valid MATLAB code. You seem to be mixing up languages.

Hi Noah,
The following code might be helpful :
x = 0:0.1:3;
y = -2:0.13:2;
Load = 10;%Integer that we want the elements to replace with
for i = 1:31
if y(i)==0;
end
end
Hope this helps!
Regards,
Pratyush.
