Class interp_nearest_neigh (o2scl)

O2scl : Class List

template<class vec_t, class vec2_t = vec_t, class fp_t = double>
class interp_nearest_neigh : public o2scl::interp_base<vec_t, vec_t, double>

Nearest-neighbor interpolation.

Nearest interpolation requires no calls to allocate() or free() as there is no internal storage required.

Public Functions

inline interp_nearest_neigh()

inline virtual ~interp_nearest_neigh()

inline virtual void set(size_t size, const vec_t &x, const vec2_t &y)

Initialize interpolation routine.

inline virtual fp_t eval(fp_t x0) const

Give the value of the function \( y(x=x_0) \) .

inline virtual fp_t deriv(fp_t x0) const

Give the value of the derivative \( y^{\prime}(x=x_0) \) .

inline virtual fp_t deriv2(fp_t x0) const

Give the value of the second derivative \( y^{\prime \prime}(x=x_0) \) (always zero)

inline virtual fp_t integ(fp_t a, fp_t b) const

Give the value of the integral \( \int_a^{b}y(x)~dx \) .

inline virtual const char *type() const

Return the type, "interp_nearest_neigh".
