Examples and How To

Choose a Solver

The general solvers (solve for symbolic solutions and numeric::solve for numeric approximations) handle a wide variety of equations, inequalities, and systems.

Solve Algebraic Systems

When solving a linear system of symbolic equations, the general solver returns a set of solutions:

Invert Matrices

To find the inverse of a matrix, enter 1/A or A^(-1):

Compute Determinants and Traces of Square Matrices

MuPAD® provides the functions for performing many special operations on matrices.

Compute Rank of a Matrix

The rank of a matrix is the number of independent rows of a matrix.

Compute Determinant Numerically

To compute the determinant of a square matrix numerically, use the numeric::det function.
