05 Nov 2009 Forward Viterbi Algorithm Forward Viterbi algorithm based on: http://en.wikipedia.org/wiki/Viterbi_algorithm Author: David Conger

foward_viterbi.m contains a bug not in the original python version. If the output is longer than 3 states then this line throws an error. The 2nd index to emit_p should be the position of the output token in the vector of possible output states, not the index into the observation vector.
p = emit_p(source_state,output) * trans_p(source_state,next_state);

12 Aug 2009 SC - powerful image rendering Useful tool for rendering and outputting information rich images Author: Oliver Woodford

The autopreservation of aspect ratio (mentioned by http://www.mathworks.com/matlabcentral/fileexchange/authors/27420) is the only thing I don't like about sc If I have a very long narrow matrix, imagesc scales it to display it in a standard sized matlab window. sc on the other hand gives me an extremely long narrow window. If there's an easy way to disable this please let me know.

Otherwise it's great.
