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 multiply(A, B,...) calculates the matrix product A B ... .  The dimensions of each matrix must be consistent with the rules of matrix multiplication.

The call multiply(A, v), for a matrix A and vector v, calculates the matrix-vector product A v. The number of entries in v must be equal to the number of columns of A. Thus if A is an n x m matrix, vectdim(v) must be m. The result is a vector with n entries.

The evalm command provides an easy method of accessing multiply.

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