MATLAB Combining 2 two-dimensional cell arrays in MATLAB

Hi

I'm quite new to MATLAB and I'm stuck on a problem which I think is probably relatively simple. Any help much appreciated!

Right, I have 2 cells, both of dimension 51x1 called n_cbc and n_load. Each of the 51 rows in the n_cbc cell contains a 5x1 matrix. Each of the 51 rows in the n_load cell contains a 3x1 matrix.

What I want to do is create a new 3rd cell that contains the data from these 2 cells. It should also be of dimension 51x1 and each row should now have a 8x1 matrix (the first 5 values from n_cbc and the next 3 values from n_load).

I always end up with a 51x2 cell, but I want all values in the one column.

Hope that made sense. Any ideas?

Thanks!

I'd suggest using a 'for' loop (you probably want to do this in an m-file). In it, you'd iterate 51 times and within each iteration, you'd concatenate the two vectors (e.g. c = [a, b];)

For loop:

M-files (in case you didn't know):

ok, thanks. it worked using this

for i = 1:51
[nodes{i}] = [n_cbc{i};n_load{i}];
end
