I have a problem. I worked with some convex problems but in this case I’m puzzled!
I would be grateful if you could help me to solve it
I want to minimize the below norm using a Marquardt algorithm when I increase the p gradually (p=2,4,8,…) to find ϕk.
Ak, fk=kf0, N, fmax, F, T0 and Ts, all are known parameters.
actually t=tTs (sampled data)
how should I code the problem to find the ϕk?
