As this was a "warning" about the reported result rather than an "error" that prevented analysis you … WebMany convex optimization problems involve constraining matrices to be positive or negative semidefinite (e.g., SDPs). You can do this in CVXPY in two ways. The first way is to use Variable ( (n, n), PSD=True) to create an n by n variable constrained to be symmetric and positive semidefinite. For example,
