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(matrix)
COND Condition Number. Finds the 1-norm (column norm) of a
square matrix.
COND(matrix)
CROSS Cross Product of vector1 with vector2.
CROSS(vector1, vector2)
DET Determinant of a square matrix.
DET(matrix)
DOT Dot Product of two arrays, matrix1 and matrix2.
DOT(matrix1, matrix2)
EIGENVAL Displays the eigenvalues in vector form for matrix.
EIGENVAL(matrix)
EIGENVV 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)
IDENMAT Identity matrix. Creates a square matrix of dimension
size × size whose diagonal elements are 1 and off-
diagonal elements are zero.
