Detailed Description

template<class T, class Prop, class Storage, class Allocator = typename SeldonDefaultAllocator<Storage, T>::allocator>
class Seldon::Matrix_SymComplexSparse< T, Prop, Storage, Allocator >

Symmetric complex sparse-matrix class.

Symmetric sparse matrices are defined by: (1) the number of rows and columns; (2) the number of non-zero entries; (3) an array 'ptr_' of start indices (i.e. indices of the first element of each row or column, depending on the storage); (4) an array 'ind_' of column or row indices of each non-zero entry; (5) values of non-zero entries.

: Complex sparse matrices are defined in the same way except that real and imaginary parts are splitted. It is as if two matrices were stored. There are therefore 6 arrays: 'real_ptr_', 'real_ind_', 'real_data_', 'imag_ptr_', 'imag_ind_' and 'imag_data_'.

: Finally, since the matrix is symmetric, only its upper part is stored.

		long	imag_nz,
		typename Matrix_SymComplexSparse< T, Prop, Storage, Allocator > ::pointer	imag_values,
		long *	imag_ptr,
		int *	imag_ind
	)

Redefines the matrix.

It clears the matrix and sets it to a new matrix defined by arrays 'real_values' (values of the real part), 'real_ptr' (pointers for the real part), 'real_ind' (indices for the real part), 'imag_values' (values of the imaginary part), 'imag_ptr' (pointers for the imaginary part) and 'imag_ind' (indices for the imaginary part).

Parameters

i	number of rows.
j	number of columns.
real_nz	number of non-zero entries (real part).
real_values	values of non-zero entries for the real part.
real_ptr	row or column start indices for the real part.
real_ind	row or column indices for the real part.
imag_nz	number of non-zero entries (imaginary part).
imag_values	values of non-zero entries for the imaginary part.
imag_ptr	row or column start indices for the imaginary part.
imag_ind	row or column indices for the imaginary part.

Warning: On exit, arrays 'real_values', 'real_ptr', 'real_ind', 'imag_values', 'imag_ptr' and 'imag_ind' are managed by the matrix. For example, it means that the destructor will release those arrays; therefore, the user mustn't release those arrays. Moreover 'j' is assumed to be equal to 'i' so that 'j' is discarded.
