Given an input element x, and the dimensions, (m, n) return a matrix of size m x n filled with element x. This must be done in less than half the time that repmat(x, m, n) takes. This is the sequel to http://www.mathworks.com/matlabcentral/cody/problems/1237-it-s-race-time-write-a-faster-function-than-the-test-suite-call-of-unique.
Example: Input: repl_mat(2, 2, 5) Output: [2, 2, 2, 2, 2; 2, 2, 2, 2, 2];

This doesn't seem to be possible anymore: http://stackoverflow.com/questions/28722723/matlab-bsxfun-no-longer-faster-than-repmat. Any chance of updating the problem with looser time tolerances?
This problem is meanless!
The solutions passed are not always fast than repmat, or just cheat(ex. using "tic")
