Template Class identity_matrix

Defined in File matrix.hpp

Inheritance Relationships

Base Type

public cif::matrix_expression< identity_matrix< float > > (Template Class matrix_expression)

Class Documentation

template<typename F = float> class identity_matrix : public cif::matrix_expression<identity_matrix<float>>

implementation of symmetric matrix_expression with a value of 1 for the diagonal values and 0 for all the others.

matrix is m x n, addressing i,j is 0 <= i < m and 0 <= j < n element m i,j is mapped to [i * n + j] and thus storage is row major

Template Parameters: F – The type of the stored values

Public Types

using value_type = F : the value type

Public Functions

inline identity_matrix(std::size_t n): constructor taking a dimension n

inline constexpr std::size_t dim_m() const: Return dimension m.

inline constexpr std::size_t dim_n() const: Return dimension n.

inline constexpr value_type operator()(std::size_t i, std::size_t j) const: Return the value of element [ i, j ]
