Description

R (iWRICES) OPERATIONS SRAD Returns the spectral radius of a square

matrix. The spectral radius is the

absolute value of the largest eigenvalue

of the matrix.

R (MATRICES) OPERATIONS OOND Retimis the cohmm-norm condition

number of a square matrix. The

condition number is defined to be the

product of the column norm of a square

matrix and the colunui norm of its

inverse.

0 (MATRICES) OPERATIONS RANK

Returns an estimate of the rank of a

matrix. The rank of a matrix is equal to

the luunber of non-zero singular values

of the matrix. If flag -54 is clear

(default), RANK treats any computed

singular value less than 10“^'* times the

size of the largest computed singular

value as zero. If flag -54 is set, RANK

comits all non-zero singular values no

matter what their size.

0 CMATRICES) OPERATIONS DET

Returns the determinant of a square

matrix. DET checks flag -54, and will

refine its computed value only if -54 is

clear (default).

0 (MATRICES) OPERATIONS TRACE

Returns the trace of a square matrix.

The trace of a matrix is equal to the

smn of the diagonal elements and also

equal to the sum of the eigenvalues of

the matrix.
