## Detailed Description

### template<class T, class TRI, class L, class A>
class boost::numeric::ublas::hermitian_matrix< T, TRI, L, A >

For a -dimensional matrix and , every element is mapped to the -th element of the container for row major orientation or the -th element of the container for column major orientation. And , .

Orientation and storage can also be specified, otherwise a row major and unbounded array are used. It is not required by the storage to initialize elements of the matrix. Moreover, only the given triangular matrix is stored and the storage of hermitian matrices is packed.

See http://en.wikipedia.org/wiki/Hermitian_matrix for more details on hermitian matrices.

Template Parameters:

  | T | the type of object stored in the matrix (like double, float, complex, etc...)
  | TRI | the type of triangular matrix is either `lower` or `upper`. Default is `lower`
  | L | the storage organization. It is either `row_major` or `column_major`. Default is `row_major`
  | A | the type of Storage array. Default is .
