nlopt solver optimization, implements different optimization algorithms , implemented in different languages.
in order use ld_lbfgs algorithm in julia, variable have vector opposed matrix?
if yes, once need optimize objective univariate function of matrix variable, have vectorize matrix able use package?
yes, nlopt understands vectors of decision variables. if code more naturally expressed in terms of matrices, should convert vector matrix in function , derivative evaluation callbacks using reinterpret.
