Lasso function provides regularized least-squares regression using lasso or elastic net algorithms. You can use below syntax to execute lasso function:
B = lasso(X,Y)
[B,FitInfo] = lasso(X,Y)
[B,FitInfo] = lasso(X,Y,Name,Value)
Follow the instructions in the link for lasso function .

I didn't know about that lasso function. I assumed he meant something like the lasso tool in Photoshop, but maybe not. The Photoshop-like tool is called imfreehand() in MATLAB. Maybe he can clarify.

@ Sanket Mishra I have tried this function before and is worked well, however, the PredictorNames character vector i found is empty and instead of having the predictor names existed in x ????
