QR
QR Factorization. Factors an m×n matrix into three matrices:
{[[m×m orthogonal]],[[m×n uppertrapezoidal]],[[n×n
permutation]]}.
QR(matrix)
RANK
Rank of a rectangular matrix.
RANK(matrix)
ROWNORM
Row Norm. Finds the maximum value (over all rows) for the
sums of the absolute values of all elements in a row.
ROWNORM(matrix)
RREF
Reduced Row Echelon Form. Changes a rectangular matrix to
its reduced row-echelon form.
RREF(matrix)
SCHUR
Schur Decomposition. Factors a square matrix into two
matrices. If matrix is real, then the result is
{[[orthogonal]],[[upper-quasi triangular]]}.
If matrix is complex, then the result is
{[[unitary]],[[upper-triangular]]}.
SCHUR(matrix)
SIZE
Dimensions of matrix. Returned as a list: {rows,columns}.
SIZE(matrix)
SPECNORM
Spectral Norm of matrix.
SPECNORM(matrix)
SPECRAD
Spectral Radius of a square matrix.
SPECRAD(matrix)
SVD
Singular Value Decomposition. Factors an m × n matrix into
two matrices and a vector:
{[[m × m square orthogonal]],[[n × n square orthogonal]],
[real]}.
SVD(matrix)
SVL
Singular Values. Returns a vector containing the singular
values of matrix.
