Performs computations associated with matrices: Solves systems of linear equations, finds sum, difference, product, determinant, trace, inverse, adjoint, transpose, eigenvalues, eigenvectors, LU factors, QR factors, tests for definiteness, etc.

Numerically solves systems of simultaneous nonlinear equations. It can fully explore defined intervals to search for multiple solutions or quickly find solutions starting with random seeds.

Performs numerical multiple integration. The limits of integration need not be constants.

Finds the relative maxima and minima of functions of several variables in a given interval. You control the maximum error in the computations. Intervals may be explored in search of multiple solutions.
