Hi all,
I am trying to combine all the outputs of a for loop into one large matrix. All the outputs are matrices. Here is my code so far.
s = 1:100; d = reshape(s, [10 10])';
d = mat2cell(d, ones(1,10), 10);
k2 = length(d) * 5;
for k1 = 1:length(d)
samp1{k1} = randsample(d{k1,1}, k2, true);
samp2 = reshape(samp1{1,k1},length(d), 5)';
end
Thanks for any help you can give.
Regards.

out=[];
for k1 = 1:length(d)
samp1{k1} = randsample(d{k1,1}, k2, true);
samp2 = reshape(samp1{1,k1},length(d), 5)';
out=[out;samp2];
end
