Re: [Haskell-cafe] Linear programming in Haskell

I think that GSL does not include linear programming solvers, but in the GSL home page there is a reference to the GLPK package: http://www.gnu.org/software/glpk/glpk.html I have not used it, but it would be very nice to have a simple Haskell interface to GLPK (or other similar library) in hmatrix or as a separate package. I will take a look at this. Alberto Daniel Peebles wrote:

As far as I can see, you'd use that for systems of linear /equalities/, but for systems of linear /inequalities/ with a linear objective function, it's not suitable. I may be wrong though :)

I have never used this part of hmatrix, but does Numeric.LinearAlgebra satisfy your needs? In particular, see linearSolve[1] and linearSolveR[2].
