Could anyone help me to solve the error in the following code

load fisheriris
X = meas;
Y = species;
Mdl = fitcknn(X,Y,'NumNeighbors',5,'Standardize',1)
predictedY = resubPredict(Mdl)
C=confusionmat(Y,predictedY)
plotconfusion(Y,predictedY)

When i run the code i am getting error in line plotconfusion(Y,predictedY).I am using matlab version 2015a.Could anyone please help me on this.

i am getting error in line plotconfusion(Y,predictedY)

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{:});

Check your input Y.

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.
