## Complexity of a quadratic program

I'm trying to compute the complexity of the quadratic program: $$\displaystyle\min_{\mathbf{X}} (\mathbf{X^TQX +C^TX}) \quad{} \text{subject to} \quad{} \mathbf{A X \leq Y}$$
A is MxN and X is Nx1. Q is positive definite and I'm using the interior point method. Any help in computing the complexity would be appreciated.
