WebRegressionLinear is a trained linear model object for regression; the linear model is a support vector machine regression (SVM) or linear regression model. fitrlinear fits a RegressionLinear model by minimizing the objective function using techniques that reduce computation time for high-dimensional data sets (e.g., stochastic gradient descent). Webfitrlinear constructed Mdl1 by training on the first four folds. Because Lambda is a sequence of regularization strengths, you can think of Mdl1 as 11 models, one for each regularization strength in Lambda. Estimate the cross-validated MSE.
