HP 39g+ Graphing manual Det, Dot, Eigenval, Eigenvv, Idenmat, Inverse, Lsq, Makemat

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
