u=argmin{||X-A*w-B*v||^2}

Inputs : A,B,X,w,v

outputs:u which contain optimized vector of w,v

how to write code for this.Please help me

[Murali Krishna AG]

All the inputs are vectors

You can use fminunc(): https://www.mathworks.com/help/optim/ug/fminunc.html or fmincon():https://www.mathworks.com/help/optim/ug/fmincon.html to find the optimal w and v.
