WebB = lasso (X,y) returns fitted least-squares regression coefficients for linear models of the predictor data X and the response y. Each column of B corresponds to a particular regularization coefficient in Lambda. By default, lasso performs lasso regularization using a geometric sequence of Lambda values. example.
