I have a problem aith a code. I have 2 matrices , A and B. Matrix A has 3x3 dimensions, while matrix B has 1x3 dimensions. I would like to minus (remove with "-"), the (1,1) number of B from each one number (each line) of the 1st column of A matrix.
After that, I I would like to minus (remove with "-"), the (1,2) number of B from each one number (each line) of the 2nd column of A matrix.
Last, I would like to minus (remove with "-"), the (1,3) number of B from each one number (each line) of the 3rd column of A matrix.
I tried these commands:
ndata=size(A,1)
[rows columns] = size(B);
for jj=1:size(A,1);
for zz=(columns);
MINUS(jj)=(A(:,jj))- B(1,zz);
end
end
but no use. Could you please help me?

"One potential reason to use a for loop would be if the poster is using an older release of MATLAB, one that predates the introduction of implicit expansion"
