I need to remove the rows that have same minimum and maximum values , below is the code used .

but it gives error:

Unable to perform assignment because brace indexing is not supported for variables of this type.

Kindly help

m = min([XTrain{:}],[],2);
M = max([XTrain{:}],[],2);
idxConstant = M == m;
for i = 1:numel(XTrain)
    XTrain{i}(idxConstant,:) = [];
end

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,:) = [];
