Without specifying the error, how do you expect us to help you? You should specify the error.

This was the error i am getting
Error using plotconfusion>standard_args (line 249)
Value{1,1} is not numeric or logical.
Error in plotconfusion (line 105)
update_args = standard_args(args{:});

plotconfusion(categorical(Y),categorical(predictedY))
This will possibly not work if you are still using that old 2015 version of MATLAB you were using before.
