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!
