DET(matrix)
This function finds the determinant of a square
matrix. See page 174 for an example of its use
in finding an inverse matrix.

DOT([vector],[vector])
This function returns the dot product of two vectors. Vectors for this function
are written as single row matrices.

IDENTMAT(size)
This function creates an n x n square matrix which is an identity matrix. For
example, IDENTMAT(4) would produce a 4x4 identity matrix for use or
storage.
