Public Functions

inline funct_multip_transform_tl()¶

inline ~funct_multip_transform_tl()¶

template<typename func_t, class fp_t> inline int eval_tol_err(char mode, func_t &&f, const fp_t &t, fp_t &val, fp_t &err, double tol_loc = -1) const¶

Evaluate the function and return the error estimate with the specified tolerance.

If tol_loc is positive and non-zero, then this is the relative tolerance used. If tol_loc is zero or negative and tol_rel is positive and non-zero, then tol_rel is used for the relative tolerance. Otherwise, if both of these values is negative, then the default relative tolerance is used.

template<typename func_t, class fp_t> inline int eval_err_iu(func_t &&f, const fp_t &x, fp_t &val, fp_t &err) const¶: Evaluate the function and uncertainty with a transformed upper limit with the default tolerance for the specified type.

template<typename func_t, class fp_t> inline int eval_err_il(func_t &&f, const fp_t &x, fp_t &val, fp_t &err) const¶: Evaluate the function and uncertainty with a transformed lower limit with the default tolerance for the specified type.

template<typename func_t, class fp_t> inline int eval_err_i(func_t &&f, const fp_t &x, fp_t &val, fp_t &err) const¶: Evaluate the function and uncertainty with a transformed limits with the default tolerance for the specified type.

template<typename func_t, class fp_t> inline fp_t eval_iu(func_t &&f, const fp_t &x) const¶: Evaluate the function with a transformed upper limit with the default tolerance for the specified type.

template<typename func_t, class fp_t> inline fp_t eval_il(func_t &&f, const fp_t &x) const¶: Evaluate the function with a transformed lower limit with the default tolerance for the specified type.

template<typename func_t, class fp_t> inline fp_t eval_i(func_t &&f, const fp_t &x) const¶: Evaluate the function with a transformed limits with the default tolerance for the specified type.
