Given a matrix, how can I slice a matrix given the input parameters are the number of rows and number of columns? See example.

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

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
