There is one prototype of lanhe
available, please see below.
lanhe( const char norm, const MatrixA& a );
lanhe (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines CLANHE and ZLANHE. lanhe returns the value of the one
norm, or the Frobenius norm, or the infinity norm, or the element of
largest absolute value of a complex hermitian matrix A.
Description =====
lanhe returns the value
lanhe = ( max(abs(A(i,j))),
NORM = 'M' or 'm' ( ( norm1(A), NORM = '1', 'O' or 'o' ( ( normI(A),
NORM = 'I' or 'i' ( ( normF(A), NORM = 'F', 'f', 'E' or 'e'
where norm1 denotes the one norm of a matrix (maximum column sum), normI denotes the infinity norm of a matrix (maximum row sum) and normF denotes the Frobenius norm of a matrix (square root of sum of squares). Note that max(abs(A(i,j))) is not a consistent matrix norm.
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type MatrixA.
The type of values is obtained through the value_type
meta-function typename value_type<MatrixA>::type. The dispatching table below illustrates
to which specific routine the code path will be generated.
