Could anyone help me to solve the error undefined operator

Undefined operator '==' for input arguments of type 'cell'.

Error in five (line 32)

acc = sum(YPred == YTest)./numel(YTest);

YPred and/or YTest are cells which can contain any kind of data, also tables, graphical objects. for that reason there is no operator for the cell. it you want to compare the content of the cell and it contains e.g. a matrix, you can use cell2mat on your variables in the formular or use suitable brackets (e.g. YPred{:} )

Could you help me how the formula acc = sum(YPred == YTest)./numel(YTest) can be written.

I tried with acc = sum(YPred{:}, YTest{:})./numel(YTest) and getting error again.

sum(YPred{:}==YTest{:})/ numel(YTest{:})

should work, you forget the comparison operator ;) and it then has to be numel(YTest{:})
