%Load Data
load fisheriris;
%The variable meas contains measurements on the sepal length, sepal width,
%petal length, and petal width for 150 iris specimens from the
%following three species :
labels = unique(species);
disp(labels);
%Train a Linear Discriminant Analysis (LDA) Classifier
mdl = ClassificationDiscriminant.fit(meas,species);
%Predict Species Using the LDA Model
predicted_species = predict(mdl,meas);
%Compute and Visualize the Confusion Matrix
Conf_Mat = confusionmat(species,predicted_species);
disp(Conf_Mat);
%We can visualize the same using a heat map.
h = heatmap(Conf_Mat);
