Matrix multiplication of matrix sequences

Question

I searched for a way to do a sequential matrix multiplication similarly to the sum(A,dim) or prod(A,dim) operations do for the sum or the element-wise multiplication.

for example:

A = arrayfun(@(x) rand(5), 1:n, 'UniformOutput', false);
P = A{1} * A{2} * ... * A{n};  % <-- search for an elegant way to do this

I would use it to multiply a large number of Transfer matrices.

Answer 1

Use a for loop for this. It is what an 'elegant' method would do eventually.

P = A{1};
for i=2:length(A), P = P * A{i}, end
