SVD(<matrix>)
This function performs a Singular Value Decomposition on an m × n matrix. The result is two matrices and a
vector:
{[[m × m square orthogonal]],[[n × n square orthogonal]],[real]}.
SVL(<matrix>)
This function returns a vector containing the singular values of the supplied matrix.
TRACE(<matrix>)
This function finds the trace of a square matrix. The trace is equal to the sum of the diagonal elements or the
sum of the eigenvalues.
TRN(matrix)
This function returns the transpose of an n x m matrix.
