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 call extend(A, m, n, x) returns a new matrix which is a copy of the matrix A with m additional rows and n additional columns. The new entries are initialized to x.

If the optional fourth argument x is omitted, then the matrix is extended by m rows and n columns but the entries in those rows and columns are not assigned.

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