SVL
QR Factorization. Factors an my.n matrix into three matrices:
I \[mxm orthogonal]],[[mxn uppertrapezoidaI\]X\nxn
permutation]] j.
QR(matrix)
Rank of a rectangular matrix.
RANK{matrLx)
Row Norm. Finds the maximum value (over all rows) for the
sums of the absolute values of all elements in a row.
ROWNORM(;7¡arr/,v)
Reduced Row Echelon Form. Changes a rectangular matrix to
its reduced row-echelon fomi.
RREF(«70irLv)
Schur Decomposition. Factors a square matrix into two
matrices. If matrix is real, then the result is
{]{orthogonaI]],[[upper-ciuasi triangular]]].
If matrix is complex, then the result is
{{[unitary]].{{upper-triangular]]}.
5CWR(matrix)
Dimensions oï matrix. Returned as a list: ¡rows,columns|.
SYZE{matri.\)
Spectral Norm of matrix.
SPECNORM(mafrü)
Spectral Radius of a square matrix.
SRRCRAR){matrix)
Singular Value Decomposition. Factors an m x n matrix into
two matrices and a vector:
{[\m X m square orthogonal]],[[n x n square orthogonal]],
[real]].
S\rD{matrix)
Singular Values. Returns a vector containing the singular
values of matrix.
