> numpy.linalg.eigvalsh(MyMatrix)
takes very long. I noticed it utilizes only a single core of my CPU.
How would one go about speeding the calculation? Specifically, I'm looking for a solution using parallel computation, or maybe something which is "more compiled".
Thank you.SageMathematicianSat, 01 Dec 2018 19:10:10 +0100https://ask.sagemath.org/question/44531/
