There's DLL for tropical math, based on AngouriMath.

Solution structure:

• TropApprox -- DLL development
• TropApproxDemo -- Console application for demonstration of TropApprox's possibilities
• TropApproxTests -- tests for TropApprox's functions

TropApprox DLL can:

• calculate in terms of tropical math
  • MaxPlus-, MinPlus-, MaxTimes- and MinTimes- algebras are built in,
• do next matrix operations:
  • find track,
  • find tropical determinant analogue,
  • find spectral radius,
  • create zero matrix,
  • create identity matrix,
  • add matrices,
  • multiplicate matrices,
  • multiplicate scalar and matrix,
  • check on equality matrices,
• approximate
  • convex functions with tropical polynomial (in terms of MaxPLus- and MinPlus- algebras),
  • elementary continuous functions with tropical rational function (in terms of MaxPlus-algebra),
• solve two sided vector equations or find pseudo-solution.

Also TropApprox have extension class for AngouriMath's Entity.Matrix that allow to write more fluent-styled code
