Matrix Functions,

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 (mato)
SIZE
Dimensions of
matrix.
Returned as a list: {rows,columns}.
SIZE [matrix)
SPECNORM
Spectral Norm of the specified array.
SPECNORM
(mato)
SPECRAD
Spectral Radius of a square
matrix.
SPECRAD
(marnx)
SVD
Singular Value Decomposition. Factors an
mXn matrix
into two
matrices and a vector:
{[
[mxm square orthogonal]
]
,
[ [nxn
square orthogonal]
]
,
[real]
}.
SVD [matrix)
SVL
Singular Values. Returns a vector containing the singular values
of
matrix.
SVL [matrix)
TRACE
Finds the trace of a square
matrix.
The trace is equal to the sum
of the diagonal elements. (It is also equal to the sum of the
eigenvalues.)
TRACE [matrix)
TRN
Transposes
matrix.
For a complex matrix, TRN finds the
conjugate transpose.
