21 Apr 2013 Imsplit Split image or matrix into subparts using simple syntax. Author: Jurgen

Thanks. I use linear indexing (lines93-95). Will fix if I have time. For now add at the end of the main function (outside for loop) "BLKS = permute(reshape(BLKS,fliplr(N)),fliplr(DIMS));"

Sorry I meant:
"BLKS = permute(reshape(BLKS,fliplr(N)),fliplr(DIMS));"
22 Feb 2013 Block Division using cell Using cell data type one can effectively breaks the 2D/3D data in to required no. of blocks. Author: Suraj Kamya

See imsplit (File ID: #40173) for more options.

Also, cell2mat should be an faster way to glue the blocks back together.
01 Feb 2013 GETCLIM: Suggest appropriate values for colormap limits Determines thresholds such that 2% of data values will be mapped to the extremes of the colormap Author: Andrew Davis

A better version of matlabs stretchlim.
Better because:
- Stretchlim returns 0-1 normalized thresholds, regardless of input class.
- Stretchlim fails with int16 even though the help says it can be used
- Any data from single or double class must be in the 0-1 range.

That said, I personally prefer 1 output vector containing both values, like with stretchlim.

29 Jan 2013 mat2im Convert 2D matrix to a 3D image matrix as used by the image processing toolbox Author: Rob Campbell

Hi I made some changes to this:
- for uint8 use limits [0 255] instead of [1 256] etc.
- Expanded input checking logic
- Changed output type to single
- Some edits to comments

Your code is working good but after dividing an image in to blocks it does not combine back as original.. one, even if you use cell2mat..
