Matrices 205
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.
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.
TRN(matrix)
