10 Mar 2014 VChooseK Choose K elements from a vector - MEX: 100 times faster than NCHOOSEK Author: Jan Simon

@Jan: great function!

For those using Linux, you need to compile using:
'mex -O CFLAGS="\$CFLAGS -std=c99" VChooseK.c'

There is a small mistake in the description in 'VChooseK.m', indicating to compile as:
mex CFLAGS="\$CFLAGS -std=C99" -O VChooseK.c

For those who run into an error because attempting to get a too large number of combinations:

-> Edit Line 94 in 'VChooseK.c':
'#define ERROR_LIMIT 1000000000L // 1 GB (recommended for 32&64 bit systems)'
to something bigger. Keep in mind to have enough memory available

-> recompile the source code

Works great, works fast. Just fine for me...

@Prasad and others wondering: The error results from using Matlab < R2011a, and missing functionalities in this version that I would not know how to omit otherwise. Sorry for that...

Very useful tool. Definitely a must if you work with spectral images in matlab. Something like this was missing in the image processing toolbox.

Very useful tool for visualizing hyperspectral images

01 Aug 2013 hyperspectral image cube slicer Image slicer to visualize multi-channel image data. Author: Timo Eckhard Kalane, Prasad

When I run the code(MATLAB 7.8/R2009a) following error comes

??? Error using ==> im_cube_slicer at 81
This hg object does not fire this event

Error in ==> im_cube_slicer_demo at 27
fh = im_cube_slicer(im_norm,lambda,s_factor,'fixed');

how to solve this error...?
