Is Constrained Nonlinear Optimization available in complex space?

As we know that the Optimization Toolbox can solve mathematical programming problem. But can it solve the methematical programming problems in complex space? For example, there is a constrained equality Ax=b, where A is a matrix in complex space, x is a vector in real space, and b is a vector in complex space. All the variables in objective function are in real space. Can the problem above be solved by using Optimization Toolbox?

As stated in the documentation, to use complex numbers in Optimization Toolbox, take the real and imaginary parts separately, so take twice as many real equations to represent complex equations.

Thanks! I used to read help in matlab, is there any document more convinient for search key words than help?
