Miscellaneous Toolkit - idxmatrix

Function: m = idxmatrix (sz)

Create matrix of subindexes

Create a matrix with each element correspoding to its subindex in the matrix, i.e.

     m(i,j,k) = i * 100 + j * 10 + k = ijk
 

The input sz defines the size of the matrix.

Example:

 M = idxmatrix ([2 3 2])
 ans(:,:,1) =

   111   121   131
   211   221   231

ans(:,:,2) =

   112   122   132
   212   222   232
