So I have a matrix, that needs to be 1x52500. If it isnt, I want to pad zeroes onto the end. This is what I have, but it did not add the zeroes.
Matrix = zeros(1,52500);
if length(index) ~= length(Matrix)
padarray(index,[0 1],0,'post')
end

I don't have the image processing toolbox so not sure how you would do it with padarray but you could also do it this way
Assuming "Matrix" is your data array to pad...
[~,X] = size(Matrix);
if X < 52500
Matrix = [Matrix,zeros(1,52500-X)]
end

Where V is your vector:
V(end+1:52500) = 0
