Summing matrices without loop

6 views (last 30 days)
I have a this function
function mat(i)
which generates an nxn matrix for a value of i. There are 10000 possible values of i, hence 10000 possible nxn matrices. I want to use mat(i) in another function and sum the 10000 possible matrices. How can i do this without a loop?

all_mat = arrayfun(@mat, 1:10000, 'uniform', 0);
total = sum( cat(3,all_mat{:}), 3 );
This still uses a loop: it is just a hidden loop. It is probably less efficient than using a loop.
