matrix repetition
显示 更早的评论
Hello,
I have a matrix M of dimensions (m by n). I want to repeat this matrix 'k' number of times along the column.
For example:
If
M=[1 3 4 5;4 5 6 7;9 3 4 2]
and k=4(say),then
out=[1 3 4 5 1 3 4 5 1 3 4 5 1 3 4 5;4 5 6 7 4 5 6 7 4 5 6 7 4 5 6 7;9 3 4 2 9 3 4 2 9 3 4 2 9 3 4 2]
please help.

repmat(M, 1, 4)
(Note: your example only uses 3 repetitions for the first row)
