Dear all, Can any one help me by providing the algorithm used in (rankfeatures) function used in Bioinformatics toolbox? Regards

The rankfeatures function help lists the following references:

Theodoridis, S. and Koutroumbas, K. (1999) Pattern Recognition, Academic Press, pp. 341-342.
Huan Liu, Hiroshi Motoda (1998) Feature Selection for Knowledge Discovery and Data Mining, Kluwer Academic Publishers

If you implemented your code correctly and you get this result, then you have a theoretical research question, not a MATLAB question, and should be investigating through other resources.

If you implemented your code incorrectly then the error is on line 42, starting at column 9.

MATLAB: What is the math going on behind the rankfeature function

One usually has two options when it comes to answering the question, "What is MATLAB doing under the hood?"

The first is to look at the documentation, in this case the documentation for rankfeatures. If the algorithm is not explicitly in the docs, there are usually references to the algorithm.

The second method is to look at the code itself. Usually you can see what MATLAB is doing using the edit command, so in this case

edit rankfeatures

I can't speak to how helpful that will be in this case, because I don't have that Toolbox.
