Returns the determinant of squareMatrix

Returns a transposed matrix; each element’s (row,column) coordinates switch

Returns the Frobenius norm (

G(real

2

+imaginary

2

)) where the sum is over

all elements of a real or complex matrix

Returns a list of the normalized eigenvalues of a real or complex
squareMatrix

Returns a matrix containing the eigenvectors for a real or complex
squareMatrix

; each column corresponds to an eigenvalue

(row norm) Returns the largest of the sums of the absolute values of the
elements (magnitudes of complex elements) in each row of matrix

(column norm) Returns the largest of the sums of the absolute values of the
elements (magnitudes of complex elements) in each column of matrix

   lMatrixName

   uMatrixName

   pMatrixName

Calculates the Crout LU (lower-upper) decomposition of a real or complex
matrix

; stores the lower triangular matrix to lMatrixName, the upper

triangular matrix to uMatrixName, and the permutation matrix (which
describes the row swaps done during calculation) in pMatrixName

Calculates

 squareMatrix¹

 squareMatrix

M

 ; the closer the

product is to 1, the more stable squareMatrix can be expected to be in matrix
functions
