Plot Colormap Confusion Matrix - Heatmap

A color map confusion matrix (heat map) with various styles

A ColorMap(HeatMap)Style Confusion Matrix

This code is an alternative to the MATLAB functions plotconfusion and confusionchart.

How to Use?

[ConfMat,Accuracy] = CmapConfusionMatrix(Actual_Labels,Predicted_Labels,Cmap);   

• ConfMat : Confusion Matrix
• Accuracy : Accuracy of Classification
• Actual_Labels : True Labels
• Predicted_Labels : Output Labels
• Cmap : Colormap Style
  • Colormap Name : Select from the table below

If no Cmap argument is provided, a popup window will appear asking you to select one of the listed colormaps, and if you ignore this step or try to choose default colormap, default option will be selected automatically.(like the below)
