Still brace indexing error is getting for the for loop
Unable to perform assignment because brace indexing is not supported for variables of this type.
m = min(XTrain,[],2);
M=max(XTrain,[],2);
idxConstant = M == m;
for i = 1:numel(XTrain)
XTrain{i}(idxConstant,:) = [];
end

if XTrain is an array, then
XTrain{i}
is both meaningless and causing the error. Use
XTrain(idxConstant,:) = [];
