mat2cell2

PURPOSE ^

Break matrix up into a cell array of same sized matrices.

SYNOPSIS ^

function C = mat2cell2( X, parts )

DESCRIPTION ^

 Break matrix up into a cell array of same sized matrices.

 Useful wrapper for matlab function mat2cell.  Instead of specifying
 locations along each dimension at which to split the matrix, this
 function takes the number of parts along each dimension to break X into.
 That is if X is d1xd2x...xdk and parts=[p1 p2 ... pk]; then X is split
 into p1*p2*...*pk matricies of dimension d1/p1 x d2/p2 x ... x dk/pk. If
 di/pi is not an integer, floor(di/pi) is used.  Leftover chunks of X are
 discarded. Using a scalar p for parts is equivalent to using [p p ... p].

 So for example if X is 10*16, mat2cell2( X, [2 3] ) breaks X into 2*3
 parts, each of size 5x5, and the last column of X is discarded.

 USAGE
  C = mat2cell2( X, parts )

 INPUTS
  X       - matrix to split
  parts   - see above

 OUTPUTS
  C       - cell array adjacent submatrices of X

 EXAMPLE
  A=rand(6,10); B = mat2cell2(A,[3 3]),
