concatenating matrices a variable number of times in Matlab

Question

How can I write this is one command in Matlab (or without loop)

X=A;
for i =1:d-1
    X= cat(3, X, A);
end

I tried to use permute, and then repmat, but the singleton last dimension is eliminated automatically, so that does not help.

X = repmat(A,[1 1 d]) Look for more ways to replicate here — Divakar

Use the repmat function (see repmat doc)

X = repmat(A, [size(A), d])
