The main point is to explain the use of the Libsvm-mat Toolbox to establish a classification (regression model), the model parameters obtained in the meaning are god horse? And if the model is given an expression, the classification problem is the main example.The test data uses Libsvm-mat's own Heart_scale.mat data (an attribute matrix of 270*13, a total of 270 samples, each with 13 attributes), to facilit
