function [result3Dmatrix] = imgCut(origImgMatrix, numRows, numCols )
For example if matrix is origImgMatrix = [2 4 6 8
9 2 3 4
1 4 9 8
3 9 1 4 ];
And numRows = 2 and numCols = 2. The matrix will be split into 2 rows and 2 columns.
result3Dmatrix will output 4 matrices:
1) 2)
2 4 6 8
9 2 3 4
3) 4)
1 4 9 8
3 9 1 4

Ran in:
Read about mat2cell.
origImgMatrix = [2 4 6 8
9 2 3 4
1 4 9 8
3 9 1 4 ];
iwant = mat2cell(origImgMatrix,[2 2],[2 2]) ;
celldisp(iwant)
iwant{1,1} = 2 4 9 2 iwant{2,1} = 1 4 3 9 iwant{1,2} = 6 8 3 4 iwant{2,2} = 9 8 1 4
Also have a look on the function reshape.
