subscript assignment dimension mismatch solutions

Hello,

I am writing into a variable Q(:,:,:) in an iteration. The first iteration stores into Q(:,:,1) a matrix of 463x2. Each succeeding iteration has one less row but same number of columns. Hence, Q(:,:,2) will have 462x2 and so on. I got the error message: subscript assignment dimension mismatch. And it took me quite some time to realise this was the reason. How do I remedy this?

Since matrices can't have empty elements you can't store your iteration results into a 3D matrix. Yo u could use a cell of 2D matrices instead:

Q = cell(1, numiterations);
for iter =  1:numel(iter)
   %...
   Q{iter} = some2Dmatrix
end
