Important: The linalg package has been deprecated. Use the superseding packages, LinearAlgebra and VectorCalculus, instead.

- For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.

The function cond computes the ``standard'' matrix condition number, defined as norm(A) * norm(inverse(A)). The matrix norm is the default employed by the linalg[norm] function, namely the infinity norm (maximum row sum).

More generally, cond(A, normname) computes norm(A, normname) * norm(inverse(A), normname). This is the same measure, but using the specified norm instead of the infinity norm.

The command with(linalg,cond) allows the use of the abbreviated form of this command.
