Matrices 13-11
DET Determinant of a square matrix.
DET(matrix)
DOT Dot Product of two arrays, matrix1 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.
IDENMAT(size)
INVERSE Inverts a square matrix (real or complex).
INVERSE(matrix)
LQ LQ Factorization. Factors an m × n matrix into three
matrices:
{[[ m × n lowertrapezoidal]],[[ n × n orthogonal]],
[[ m × m permutation]]}.
LQ(matrix)
LSQ Least Squares. Displays the minimum norm least squares
matrix (or vector).
LSQ(matrix1, matrix2)
LU LU Decomposition. Factors a square matrix into three
matrices:
{[[lowertriangular]],[[uppertriangular]],[[permutation]]}
The uppertriangular has ones on its diagonal.
LU(matrix)
MAKEMAT Make Matrix. Creates a matrix of dimension rows ×
columns, using expression to calculate each element. If
expression contains the variables I and J, then the
