Ans).
Results can be displayed with single brackets (for a vector) or
double brackets (for a matrix).
Matrix Functions
COLNORM
Column Norm. Finds the maximum value (over all columns) of
the sums of the absolute values of all elements in a column.
COLNORM (mahrx)
COND Condition Number. Finds the 1-norm (column norm) of a square
matrix.
COND {matrix)
CROSS Cross Product of vector! X vector2.
CROSS (vector!, vector2)
DET Determinant of a square matrix.
DET {matrix)
DOT
Dot Product of two arrays, matrix! ■ matrix2.
DOT {matrix!, matrix2)
EIGENVAL
Displays the eigenvalues in vector form for matrix.
EIGENVAL {matrix)
EIGENW
Eigenvectors and Eigenvalues for a square matrix. Displays a list
of two arrays. The first contains the eigenvectors and the second
contains the eigenvalues.
EIGENW (marnx)
IDENMAT

whose diagonal elements equal 1 and off-diagonal elements
equal zero.
IDENMAT {size)
INVERSE
