Template Struct CSR_hermitian¶

Defined in File CSR_hermitian.hpp

Struct Documentation¶

template<typename T> struct CSR_hermitian¶

sparse matrix in compressed-sparse-row (CSR) format

template (type is expected to be double or complex<double>) Only the lower triangle and the diagonal are stored

Public Functions

inline void apply(const vector<T> &x, vector<T> &y)¶: Applies the matrix on a vector x and adds the result to vector y.

inline void apply(const vector<T> &x, vector<T> &y, T z)¶: Applies the matrix on a vector x and adds z times the result to vector y.

inline void clear()¶

Public Members

vector<int32_t> J¶: array of column indices

vector<int32_t> Iptr¶: array of indices of J where the row index changes

vector<T> v¶: array of values of the matrix elements

vector<double> diag¶: diagonal elements (stored separately)

Friends

inline friend std::ostream &operator<<(std::ostream &s, const CSR_hermitian &m)¶: Prints the matrix if of modest size.
