is there a gradient based and mixed integer optimization algorithm in Matlab?

for a nonlinear constrained system , is there any optimization algorithm that can handle mixed integer constraints and in the same time work in the same way like GRG algorithm? by another word, to be based on gradient search method and satisfying constraints on every iteration. so,Mixed integer genetic algorithm and similar evolutionary algorithms are not fit for my problem.

my problem solution is easy to be founf by numerical algorithms. also, constraints.

any help would be appreciated .

No, the only two solvers for nonlinear integer-constrained problems are ga and surrogateopt, neither of which is gradient-based.
