plotConfMat

Plots a confusion matrix with colorscale, absolute numbers and precision normalized percentages. This is a basic alternative to MATLAB's plotconfusion if you do not have the Neural Network Toolbox. Compatible with GNU Octave.

Usage:

plotConfMat(confmat, labels, fontsize, grayscale)

• confmat (required): confusion matrix
• labels: class labels (e.g. {'Dog', 'Cat'}) (default: {'1', '2', ...})
• fontsize: to be used in plot texts (default: 14)
• grayscale: if true, use grayscale colors (default is false - use blue colors like scikit-learn)
