Re: [ojAlgo-user] how to construct a MatrixStore?

[Anders P. <an...@op...>]

I recommend you start building your optimization models using QuadraticExpressionsModel.

If you absolutely want to construct your own matrices then perhaps a PrimitiveDenseStore could be a suitable MatrixStore implementation to use.
