fmincon

For a constrained nonlinear multivariable function f(x) subject to the constraints as follows: c(x)≤0; ceq(x)=0; A·x≤b; Aeq·x=beq; lb≤x≤ub The object function and nonlinear function can have other parameters besides x.And when call fmincon just use the function handle @ respectively,for example,x = fmincon(@(x)myfun(x,m,n),x0,A,b,Aeq,beq,lb,ub,@(a,b)mycon(a,b));

I want to learn if Aeq can also have other parameters such as p,q ,The name of the .m file is myAeq for example and call fmincon like this x = fmincon(myfun,x0,A,b,@(p,q)myAeq(p,q),beq,lb,ub,@mycon);

No. fmincon() says that A, b, Aeq, and beq must be matrices. Function handles are not allowed for them. Only the objective function and the nonlinear constraint function can be function handles.

Thanks for help!If so,how can the problem as I decribed be solved？Will the function fmincon uesful then？

Linear constraints are a special case of nonlinear constraints, so you can include Aeq*x=b in your nonlinear constraint function, where you can implement them any way you wish. However, you should probably elaborate on why you don't think they should be expressed in matrix form.
