For binary SVM classification, use fitcsvm https://www.mathworks.com/help/stats/fitcsvm.html .

If you have more than 2 classes, use https://www.mathworks.com/help/stats/fitcecoc.html to train multiple SVM classifiers: "Mdl = fitcecoc(Tbl,ResponseVarName) returns a full, trained, multiclass, error-correcting output codes (ECOC) model using the predictors in table Tbl and the class labels in Tbl.ResponseVarName. fitcecoc uses K(K – 1)/2 binary support vector machine (SVM) models using the one-versus-one coding design, where K is the number of unique class labels (levels). Mdl is a ClassificationECOC model." There are many options in fitcecoc to control things like the coding design, the details of the binary learners, etc.
