I am following a simple confusion matrix tutorial. I keep getting the error "undefined function or variable 'confusionchart'". What could be the reason for this error? I am using Matlab R2018a.
[m, order] = confusionmat(target_,output_);
figure
cm = confusionchart(m,order);

Hi,
confusionchart was introduced in R2018b. Since you are using R2018a it is not available. Update to R2018b to use it.
To avoid this kind of problems, make sure to use the R2018a documentation.
Best regards
Stephan
