In optimization toolbox, in function "gamultiobj" how to define ConstraintFile.m function in which constraints are not functions of design variables. This facility is available in "ga" under "nonlin".

If the constraints are not functions of design variables, then how are they constraints?
gamultiobj gained the ability to use nonlinear constraints in R2014b, as you can see in the release notes.

Thank you Alan for finding time to answer my Q. You are right that, how constraints without design variables possible. I am working on buildings as earthquake resistant dynamic system. In which,deflection of building is indirect constraints, whereas design variables are related to damping in the system. I will sure go through release notes. Thanks once again.

If you mean that your constraints are functions not only of the design variables but also additional parameters, use the techniques described in the documentation to pass those additional parameters into the constraint functions when you call gamultiobj.
