Hi,

I am trying to solve an optimization problem and the constraint is in this form:

x’x <= t^2 + c^2;

x is a vector variable and t is a scalar variable and t>0 and c is a constant.

This shows a convex set since it is a part of a second order convex cone.

How can I write it in DCP form? Because it is Convex <= Convex form which CVX doesn’t accept it.

Thanks.
