Module rgsl::interpolation

Functions

bsearch	This function returns the index i of the array x_array such that x_array[i] <= x < x_array[i+1]. The index is searched for in the range [index_lo,index_hi].
eval	This function returns the interpolated value of y for a given point x, using the interpolation object interp, data arrays xa and ya and the accelerator acc. When x is outside the range of xa, the error code ::Dom is returned with a value of rgsl::NAN for y.
eval_deriv	This function returns the derivative d of an interpolated function for a given point x, using the interpolation object interp, data arrays xa and ya and the accelerator acc.
eval_deriv2	This function returns the second derivative d2 of an interpolated function for a given point x, using the interpolation object interp, data arrays xa and ya and the accelerator acc.
eval_deriv2_e	This function returns the second derivative d2 of an interpolated function for a given point x, using the interpolation object interp, data arrays xa and ya and the accelerator acc.
eval_deriv_e	This function returns the derivative d of an interpolated function for a given point x, using the interpolation object interp, data arrays xa and ya and the accelerator acc.
eval_e	This function returns the interpolated value of y for a given point x, using the interpolation object interp, data arrays xa and ya and the accelerator acc. When x is outside the range of xa, the error code ::Dom is returned with a value of rgsl::NAN for y.
eval_integ	This function returns the numerical integral result of an interpolated function over the range [a, b], using the interpolation object interp, data arrays xa and ya and the accelerator acc.
eval_integ_e	This function returns the numerical integral result of an interpolated function over the range [a, b], using the interpolation object interp, data arrays xa and ya and the accelerator acc.
