Follow-up Comment #1, bug #59840 (project octave):
Your timing data is acknowledged. It appears from your code that you are only
looking for 2-dimensional replication, not for 3 or more dimensions. Is this
correct? If that is the case, then that could account for speed differences.
The standard repmat and repelem use varargin to allow for multiple arguments
to maintain Matlab compatibility for calls like repmat(rand(2,3),2,3,4,5).
Would you be willing to write an improved repmat and repelem that allows for
multiple arguments while maintaining the speed of your kron-based approach?
