Hello everybody,
I have been reading the forums the whole day and trying different combinations to solve my problem but I could not get an answer yet.
T1' is a 1x50-row-vector, T_iso1 is a 50x50-square-matrix, and bsfc1 is also a 50x50-square-matrix.
I want to store in a matrix the column-vectors vq from the interpolation for every i. I can run the code and get a column vector vq for every i, but then I only store the last one. However, when I try to store them all in a matrix A I get always the error 'Subscripted assignment dimension mismatch.'
The code is the following:
lim=50;
for i=1:lim
x = T1';
xq = T_iso1(:,i);
v = bsfc1(:,i)';
vq= interp1(x,v,xq,'spline')
A(:,i) = vq;
end
Could anybody help me out? I would appreciate any comment.
Thank you very much in advance,
John

Your code runs fine for me with random inputs as follows:
Name Size
T1 50x1
T_iso1 50x50
bsfc1 50x50
Maybe you have an "A" variable floating around with a different size? Try pre-allocating "A" first. E.g.,
A = zeros(50,lim);

Oh my god! Thank you James. I have been trying so many different things today that I did not pay attention to the basics... Yes, it was exactly what you said. Thank you!
