Feature request: Matrix-valued polynomials #349

Closed sverek closed 3 years ago

sverek commented 3 years ago

Would be great to be able to have matrices as coefficients to polynomials, for example,

LaurentPolynomial([[1 2;3 4],[5 6;7 8],[10 11;12 13]],-1)

Works in ApproxFun.jl

Yeah, #234 made some attempts here, but I never merged it in. The main issue (there are others) is we expect some things to be available from the type T, such as one(T), ... and for a matrix that isn't the case, though for StaticArrays it is. At the time of #234, even the symbol wasn't in the polynomial type. Now it is. I'll have a look to see how far we can get now.
