Problem 2813. Create a block diagonal matrix
A block diagonal matrix is a square matrix that can be written as
A = [a 0 0 0 0 b 0 0 0 0 c 0 0 0 0 ...]
where a, b, c etc. are all square matrices.
Construct A such that
A = [a 0 0 0 0 a 0 0 0 0 a 0 0 0 0 ...]
where a is allowed to be non-square or empty and occurs n times. n is always an integer greater than or equal to 0.
Examples:
a = [1 2 3], n = 3
gives
A = [1 2 3 0 0 0 0 0 0 0 0 0 1 2 3 0 0 0 0 0 0 0 0 0 1 2 3]

If you know a function which is used to create a matrix, you can solve this problem easily !

I thought you referred to the function blkdiag(), but I am surprised to know that it is not the case (for a one-liner)!
