There is one prototype of hbevd
available, please see below.
hbevd( const char jobz, MatrixAB& ab, VectorW& w, MatrixZ& z );
hbevd
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSBEVD, DSBEVD, CHBEVD, and
ZHBEVD. hbevd
computes
all the eigenvalues and, optionally, eigenvectors of a complex Hermitian
band matrix A. If eigenvectors are desired, it uses a divide and conquer
algorithm.
The divide and conquer algorithm 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.
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type MatrixAB
.
The type of values is obtained through the value_type
meta-function typename value_type<MatrixAB>::type
. The dispatching table below illustrates
to which specific routine the code path will be generated.
