Keep this to Matrix-times-Matrix operators.
Btw. the interface file by Alberto gives you uniform usage of an operator symbol (<>) while retaining full type safety by functional dependencies. http://dis.um.es/~alberto/hmatrix/doc/LinearAlgebra.Interface.html This is a good solution, I think. > I feel using separate types for vectors and scalars just overcomplicates > things... I'm excited if your code gets swamped by conversions between Double and Matrix then. I really plead for representing everything with strings, this is the most simple and most flexible solution! :-] _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
