fscmrmr function outputs only zero score for all features. I don't know if this is the expected behaviour.
[idx, scores] = fscmrmr(features,Y);
results = [idx;scores];
disp(results)
%features is a matrix. In each row there is one observation. In each column there is one feature.
% Y is a logical vector (labels 1 and 0). It shows the same behaviour even if i use tables.

Without seeing the specific data posed, it is impossible to know. Can it return zero scores, yes, I would bet that is the case. In fact, I am even positive that is the case, since in a random test case I just tried, that was true. But that just means you are probably misunderstanding how the code should be used.
help fscmrmr
A quick run of the sample test problem they supply in the help shows this:
load ionosphere
[idx,scores] = fscmrmr(X,Y)
Anyway, in order to understand what you did wrong to get the results you got, you need to show the data you tried to pass into that code.
