Thanks for replying, I am still not able to actully understand to put the nonlinear equality constraint can you please help me out, say I have a cost function F(x,y) subjected to constraint g1(x,y) = constant, g2(x,y) = constant and g3(x,y) = constant. Now i can make subroutines to calculate the constraint but how do i club into n put it in the optimizer. if possible please explain.
