fitcdiscr creates a ClassificationDiscriminant object from numeric predictors X and class labels Y.
Name-value arguments include ClassNames, Prior, DiscrimType, Gamma, and Delta. Supported discriminant types are linear, quadratic, diaglinear, and diagquadratic. Prediction returns posterior class scores.
X = [0 0; 0 1; 1 0; 1 1; 5 5; 5 6; 6 5; 6 6];
Y = [1; 1; 1; 1; 2; 2; 2; 2];
mdl = fitcdiscr(X, Y);
