FloatSymQREigServer(RWBoolean computeVecs=TRUE);
DoubleSymQREigServer(RWBoolean computeVecs=TRUE);
DComplexHermQREigServer(RWBoolean computeVecs=TRUE);

Constructs a server. The parameter indicates whether this server should be configured to compute eigenvectors as well as eigenvalues.

void
FloatSymQREigServer::computeEigenVectors(RWBoolean);
void
DoubleSymQREigServer::computeEigenVectors(RWBoolean);
void
DComplexHermQREigServer::computeEigenVectors(RWBoolean);

Sets whether or not the server should compute eigenvectors as well as eigenvalues.

RWBoolean
FloatSymQREigServer::computeEigenVectors() const;
RWBoolean
DoubleSymQREigServer::computeEigenVectors() const;
RWBoolean
DComplexHermQREigServer::computeEigenVectors() const;

Returns TRUE if this server is configured to compute eigenvectors as well as eigenvalues.
