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
