Hi,
I would like to know what is the main difference between the prtools functions featrank and featseli. They require different inputs, but appear to be the same functions. Thank you very much for your comments.

featrank just ranks all features according to a user supplied criterion and returns the ranking.

featseli selects according to possibly the same criterion the best K features and returns a mapping to a subspace based on these features.

w = featseli(a,crit,k,t);

is identical to

I = featrank(a,crit,t); w = featsel(size(a,2),I(k));

Thank you.
