If they are linear constraints, they will be expressed using matrix-vector multiplication
A*x<=b
Aeq*x<=beq
so any vectorized method for building the A, Aeq, b, beq, matrices would be appropriate. Similarly, nonlinear constraints in Matlab are expressed using user-defined constraint functions of the following form
function [cineq,ceq]=nonlcon(x)
....
end
where cineq and ceq are vectors of inequality and equality constraint violations, respectively. When the number of variables or constraints is large, you would use vectorized Matlab commands to generate cineq and ceq from x.
