prtScoreConfusionMatrix

[confMat,occurances] = prtScoreConfusionMatrix(guess,truth) prtScoreConfusionMatrix Plot or return the confusion matrix CONFMAT = prtScoreConfusionMatrix(GUESS, TRUTH) returns the confusion matrix that results from comparing GUESS as compared to the truth in TRUTH. GUESS and TRUTH should both be Nx1 vectors. The elements of both TRUTH and GUESS should be binary or interger class labels. prtScoreConfustionMatrix(GUESS,TRUTH) called without any output arguments plots the confusion matrix. Example: TestDataSet = prtDataGenMary; % Create some test and TrainingDataSet = prtDataGenMary; % training data classifier = prtClassMap; % Create a classifier classifier.internalDecider = prtDecisionMap; classifier = classifier.train(TrainingDataSet); % Train classified = run(classifier, TestDataSet); % Display the confusion matrix prtScoreConfusionMatrix(classified, TestDataSet)
