Hi,
I have an array of 100 1*4 matrices
I have a second array of 1000 1*4 matrices
I want the .* of for each of my 100 matrices multiplied by each of the 1000 matrices.
In total, my ouput should be 100,000 matrics.
I just wanted some help with the code, I think i may be misunderstanding how the arrays are working...
Thanks

Hi,
If I understood what you said correctly your problem could be solved like this
A = cell array containing 1000 1*4 matrices B = cell array containing 100 1*4 matrices
C = cell(length(A),length(B));
for i = 1:1000
for j = 100
C{i,j} = A{i}.*B{j};
end
end
the for loop could be vectorized to:
for j = 100
C{:,j} = A{:}.*B{j};
end
This will give you an output cell matrix of the size 1000*100
Hope this was of help.
