多分类问题中混淆矩阵(Confusion Matrix)的Matlab画法

======================================================================== Matlab code for computing and visualization: Confusion Matrix, Precision/Recall, ROC, Accuracy, F-Measure etc. for Classification. The package runs well at Matlab(Version:R2010b) for Windows. However, it may report some errors at old version matlab, e.g., "no function 'assert'" or others. You can update yout Matlab or you can find the missing functions(.m files).
