Histc
Like histc but for n-dimension.Unlike the other nd histogram http://www.mathworks.com/matlabcentral/fileexchange/3957 beside counting, this function returns also the location of points in the bins. Coded entirely in Matlab (no mex required). Speed slightly slower (but quite decent).User can data...

This function tries to improve the slow Matlab INPOLYGON function.There are few other fast codes on FEX (e.g., by Darren Engwirda). After exploring many different ways, I come to the conclusion that Darren Engwirda's approach is close to optimal. So here you'll find a general method that share...

HISTCND is similar to HISTC, but creates a histogram with any number of dimensions.N = HISTCND(X,Y,Z,... XEDGES,YEDGES,ZEDGES,... )where N is a histogram count with dimensions length(XEDGES) x length(YEDGES) x length(ZEDGES) ...If XEDGES, YEDGES, etc. are monotonically increasing and non-NaN, a...
