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

Mates8 features:

» Basic arithmetic and polynomial operations (-,+,*,/,^,%), including GCD

» finds polynomials roots, of real or complex coefficients,

» does multivariable polynomial division,

» Lagrangian interpolation and

» basic matrix operations (-,+,*,/,^).

» May obtain the inverse matrix,

» cofactor,

» adjoint,

» transpose matrix,

» echelon form,

» Jordan form,

» eigenvalues,

» eigenvectors, and

» the determinant of an invertible matrix of real, complex, polynomial or expression entries.

» Performs derivatives using Euler's notation, e.g.: Dx(sin(x));

» Jacobian;

» approximates the 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 or indeterminate,

» as non linear system of equations.

» Also, is capable of bounded definite integrals,

» inmediate,

» trigonometric or

» partial fractions integration -quotients of polynomials integration- and

» integration by parts.

» Solve some ordinary first order differential equations with or without specifying the initial condition.

» Approximates first order diff. eqs. by Euler's method specifying the initial condition.

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