Trait Implementations

impl<T> Interpolation<T> for SteffenInterp<T>

where T: Num,

fn eval( &self, xa: &[T], ya: &[T], x: T, acc: &mut Accelerator, ) -> Result<T, DomainError>

Returns the interpolated value y for a given point x, using the data arrays xa and ya and the Accelerator acc.

fn eval_deriv( &self, xa: &[T], ya: &[T], x: T, acc: &mut Accelerator, ) -> Result<T, DomainError>

Returns the derivative dy/dx of an interpolated function for a given point x, using the data arrays xa and ya and the Accelerator acc.

fn eval_deriv2( &self, xa: &[T], ya: &[T], x: T, acc: &mut Accelerator, ) -> Result<T, DomainError>

Returns the second derivative d²y/dx² of an interpolated function for a given point x, using the data arrays xa and ya and the Accelerator acc.

fn eval_integ( &self, xa: &[T], ya: &[T], a: T, b: T, acc: &mut Accelerator, ) -> Result<T, DomainError>

Returns the numerical integral of an interpolated function over the range [a ,b], using the data arrays xa and ya and the Accelerator acc.
