I don't know how to write matlab code.
Especially, I don't understand question number 1.


Problem 1: Find the solution by gradient descent method<br>min(2x1 – 1)2 + (-x1+ x2)² + (2x2 + 1)²<br>1) Formulate the above corresponding least-squares problem(i.e., find one of possible A and b) and solve<br>it using MATLAB<br>min ||Ax – b||3<br>2) How many do suboptimal points exist ?<br>
