I need to put "a" matrix one below the other in a single matrix. That is, I need to place in a matrix of dimension a*b x N, where the first b rows correspond to sec=1, from row b+1 to row 2b+1 the second matrix corresponding to sec=2, and so on.
For example for this code:
a=100;
b=5;
N=8;
for sec=1:a
PM=rand(b,N)
end
I want to create the matrix of dimension 500x8, formed by the 100 matrix generated, where the first 5 rows correspond to the matrix obtained for sec = 1, from row 6 to row 11 the second matrix corresponding to the matrix obtained for sec = 2, and so on.

Ok, well the indexing on 'data' should be what you're looking for. I can't write the right hand side of the equation for you because I don't know what it looks like.

You can just append the matrices as they come.
a=100;
b=5;
N=8;
% inital empty matrix
PM = [];
% your loop
for sec=1:a
PM = [PM; rand(b,N)];
end
