Dear Matlab experts,
I have a issue with this function:
plotconfusion(Ytest.grade,app.predict)
When I put the tow vectors into categorical I have this error:
And when i put the two vectors into double I have again an error:
So how can I plot this confusion matrix then ?
NB: the function
app.confusionMat = confusionmat(Ytest.grade, app.predict);
works perfectly well !
Many thanks in advance !
Pierre
