How to concatenate matrices using for loop?

Dear All:

I have a group of matrices of size (100X3). If possible, I want to concatenate them in one larger matrix using a for a loop. I want to use a loop because the number of matrices differs for each run so using the command [ x1 x2 ...] is not practical.

Thank you, Aziz

How are the individual matrices stored? In individual variable names like x1, x2, etc.? Or in a cell array? Or as fields of a struct? Or ...?

Thank you for the respond. The are stored such as x{1}, x{2}..... each has the same size 68*3 elements

Thanks again

If x is a cell array, and you simply want all of them, then

result = cell2mat(x);

or if you want them stacked vertically

result = cell2mat(x');

If you want a subset of the cells, then specify the range. E.g.,

result = cell2mat(x(range));

or if you want them stacked vertically

result = cell2mat(x(range)');
