Minimize over two variables

I want to minimize the following function:-

min_{U,V} \sum_{(i,j) belong to O} (o_{i,j}-u_{i}v_{j}^{T})^{2}+ \lambda_{1}|U|^{2}+\lambda_{2}|V|^{2}.

How can I minize over two vairables in CVX

I don’t think this is convex. CVX is not your tool. But have you seen this example?
