The positive-definite question #647
Description
Hello, thank you very much for the resources you provided. I am using this library to write the quadratic optimization part, and now I have encountered a problem, the console information——RuntimeWarning: There was an error while running the linear optimizer. Original error message: linalg.cholesky: (Batch element 0): The factorization could not be completed because the input is not positive-definite (the leading minor of order 1 is not positive-definite)..warnings.warn(msg, RuntimeWarning).I would like to ask how positive definiteness is determined and how my input matrix is decomposed.
