Warning: No available confusion matrix plotting functions

[Lynton Graetz]

Using TS_Classify(mynormalizedfile) with two classes accuracy is calculated in the command output then:

Warning: No available confusion matrix plotting functions 
> In TS_Classify (line 233) 

And no classification plot is generated.
I installed Matlab 2020a and ensured I have the Stats/ML Toolbox installed and the Deep Learning Toolbox. Still get the same error.

Tested with latest version of all files.

Thanks @LJGz You're right—this is now fixed in 3ec5b13
If you pull from the master branch, this should work 👍
