There is one prototype of stedc
available, please see below.
stedc( const char compz, VectorD& d, VectorE& e, MatrixZ& z );
stedc
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSTEDC, DSTEDC, CSTEDC, and
ZSTEDC. stedc
computes
all eigenvalues and, optionally, eigenvectors of a symmetric tridiagonal
matrix using the divide and conquer 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.
This code makes very mild assumptions about floating point arithmetic. It will work on machines with a guard digit in add/subtract, or on those binary machines without guard digits which subtract like the Cray X-MP, Cray Y-MP, Cray C-90, or Cray-2. It could conceivably fail on hexadecimal or decimal machines without guard digits, but we know of none. See DLAED3 for details.
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.
