Evaluate Hessian of the Lagrangian function
h = csh(x,v)
x is the current estimate of the solution
the current estimate of the Lagrange multipliers
the Hessian of the Lagrangian
h=csh(x,v) returns the Hessian of the Lagrangian in h. h is a sparse matrix containing only the upper triangular entries.
