Hello

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.

where

Ak, fk=k*f0, N, fmax, F, T0 and Ts, all are known parameters.
actually t=t*Ts (sampled data)

how should I code the problem to find the ϕk?

Regards
