Polynomial & Math Calculator: Mates8

Mates8 does basic math and polynomial operations (-,+,*,/,^), finds polynomials roots, of real or complex coefficients, multivariable polynomial division, Lagrangian interpolation; does basic matrix operations (-,+,*,/,^), may obtain the inverse matrix of an invertible matrix of real, complex, or polynomial elements, also performs derivatives (using Euler's notation; ex.gr: Dx(sin(x))), Jacobian and resolves linear and, perhaps non linear system of equations. Also is capable of bounded definite integrals and partial fractions integration -quotients of polynomials integration- as integration by parts (see examples in Predefined/Examples menu option in the application's form).

Mates8 intends to be an improved version of previous Mates2-Mates6 calculators.

Polynomial Calculator in Excel Workbook

Mates6_2 & Mates6_3

Polynomial calculator, coded in VB.NET; employs Shunting Yard algorithm and RPN (postfix) notation.
Newer version employs an abstract syntax tree (AST) instead, does matrix operations (also performs Jacobian), multivariable polynomial division, Lagrangian interpolation and resolves linear and non linear system of equations (see examples combo box in the application's form).
