Here is a minimal example of my problem: I want to find a minimizer x that minimizes the objective function : opnorm(A*x-b,2)^2 I tried Convex.jl, but it doesn’t work for the operator norm.

If x and b are 1d arrays, this is not defined in Julia. If they are 1-column matrices, this is equivalent to the Euclidean norm. What are the dimensions here?
