I am using cplex for matlab, qcp sholver. Does the slover only permit one quadratic constraint? Because if you have several quadratic constraints, 'r' should be defined as a vector. But if I define 'r' as a vector, the solver would tell me it's wrong. And the examples are for single quadratic constraint, so, how to input the 'r' if you have multi quadratic constraints? Thanks!

And, if the quadratic constraints number is too large, e.g. more than 100. Is it necessary to input the matrix 'Q' manually? Thanks!!

It is not required to input Q manually. You can use any matlab code to create matrix Q.

CPLEX supports more than a single quadratic constraint. Maybe you can show us the offending code?
