Matrices
For row# or column#, supply the number of the row
(counting from the top, starting with 1) or the number
of the column (counting from the left, starting with 1).
The argument matrix can refer to either a vector or a
matrix.
Column Norm. Finds the maximum value (over all
columns) of the sums of the absolute values of all elements
in a column.
COLNORM(matrix)
Condition Number. Finds the 1-norm (column norm) of a
square matrix.
COND(matrix)
Cross Product of vector1 with vector2.
CROSS(vector1, vector2)
Determinant of a square matrix.
DET(matrix)
Dot Product of two arrays, matrix1 and matrix2.
DOT(matrix1, matrix2)
Displays the eigenvalues in vector form for matrix.
EIGENVAL(matrix)
Eigenvectors and Eigenvalues for a square matrix.
Displays a list of two arrays. The first contains the
eigenvectors and the second contains the eigenvalues.
EIGENVV(matrix)
Identity matrix. Creates a square matrix of dimension
size × size whose diagonal elements are 1 and off-
diagonal elements are zero.
IDENMAT(size)
203
