repmat

Replicate and tile array

Syntax

B = repmat(A,M,N)

B = repmat(A,M,N) creates a large matrix B consisting of an M-by-N tiling of copies of A.

B = repmat(A,[M N]) accomplishes the same result as repmat(A,M,N).

B = repmat(A,[M N P ...]) tiles the array A to produce an M-by-N-by-P-by-... block array. A can be N-D.

repmat(A,M,N) for scalar A is commonly used to produce an M-by-N matrix filled with values of A.

Simple examples of using repmat are

repmat(randumat(2,2),2,3) 
repmat(ureal('A',6),[4 2])
