Question
I've designed a fuzzy inference system in the MATLAB using fuzzy logic toolbox. My target dataset is comprised of 100 instances and this data set is of 21 different classes. Now, I want to calculate its ARP (Accuracy, Recall and Precision) for every class which means there will be 21 different confusion matrix with 21 different ARPs.   I've seen 'plotconfusion' and 'confusionmat' functions of the MATLAB but didn't understand these function. Kindly guide me to create the confusion matrix for my system and how to calculate it in MATLAB.
