There is one prototype of steqr
available, please see below.
steqr( const char compz, VectorD& d, VectorE& e, MatrixZ& z );
steqr (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSTEQR, DSTEQR, CSTEQR, and
ZSTEQR. steqr computes
all eigenvalues and, optionally, eigenvectors of a symmetric tridiagonal
matrix using the implicit QL or QR method. The eigenvectors of a full
or band complex Hermitian matrix can also be found if ZHETRD or ZHPTRD
or ZHBTRD has been used to reduce this matrix to tridiagonal form.
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type VectorD.
The type of values is obtained through the value_type
meta-function typename value_type<VectorD>::type. The dispatching table below illustrates
to which specific routine the code path will be generated.
