I have matlab R2016a program on my computer, I want to use the mRMR feature selection algorithm so I found this function in MATLAB Help:
idx = fscmrmr(Tbl,ResponseVarName)
but unfortunately in MATLAB 2016, this function is not defined.
IU wanted to ask if there is a sustitution for fscmrmr, I'll be very thankful to have your opinions.

This function was introduced in Statistics and Machine Learning Toolbox in release R2019b according to the note at the end of its documentation page. You will need to use release R2019b or later and have Statistics and Machine Learning Toolbox installed and licensed to use it.
I'm not sure how difficult it would be for you to implement your own version of this function in release R2016a. The documentation page lists two references that may be of use if you want to try that.

@Steven Lord In Mathwork page did you refer to these articles?
:[1] Ding, C., and H. Peng. "Minimum redundancy feature selection from microarray gene expression data." Journal of Bioinformatics and Computational Biology. Vol. 3, Number 2, 2005, pp. 185–205.

Those are the references on the documentation page, yes.
