Mates8 is the downloadable version of the Online Polynomial and Scientific Calculator.

Mates8 does basic math and polynomial operations (-,+,*,/,^,%), finds polynomials roots, of real or complex coefficients, multivariate polynomial division, Lagrangian interpolation and basic matrix operations (-,+,*,/,^). May obtain the inverse, cofactor, adjoint and transpose matrix and the determinant of an invertible matrix of real, complex, polynomial or expression entries. Finds eigenvalues, eigenvectors and Jordan form of a matrix. Performs derivatives using Euler's notation, e.g.: Dx(sin(x)); Jacobian; (approximation to) exponential matrix (e.g. exp(1,cos(x)|0,1)=(2.718..,2.718...*cos(x)|0,2.718...)); resolves linear, when compatible and determinate, as non linear system of equations and may solve some ordinary first order differential equations with or without specifying the initial condition.

Also is capable of bounded definite integrals, inmediate, trigonometric or partial fractions integration -quotients of polynomials integration- and integration by parts.

You may find examples in Predefined/Examples menu option of the application's form.

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