matrix
norm matrix
Returns the Frobenius norm ( G(real
all elements of a real or complex matrix
Returns a list of the normalized eigenvalues of a real or complex
eigVl squareMatrix
squareMatrix
eigVc squareMatrix Returns a matrix containing the eigenvectors for a real or complex
squareMatrix; each column corresponds to an eigenvalue
rnorm matrix (row norm) Returns the largest of the sums of the absolute values of the
elements (magnitudes of complex elements) in each row of matrix
cnorm 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
LU( matrix , Calculates the Crout LU (lower-upper) decomposition of a real or complex
lMatrixName , matrix; stores the lower triangular matrix to lMatrixName, the upper
uMatrixName , triangular matrix to uMatrixName, and the permutation matrix (which
