Member Function Documentation

get()

template<typename T>

real_t qlibs::interp1::get ( const T x )

inlinenoexcept

Interpolate input point x to determine the value of y at the points xi using the current method. If value is beyond the endpoints, extrapolation is performed using the current method.

Parameters

[in]

x

The input point.

Returns

The interpolated or extrapolated y value.

setData() [1/2]

bool qlibs::interp1::setData ( const real_t *const xTable, const real_t *const yTable, const size_t sizeTable )

inline

Set the data table for the 1D interpolation instance.

Parameters

[in]	xTable	An array of size sizeTable with the x points sorted in ascending order.
[in]	yTable	An array of size sizeTable with the y points.
[in]	sizeTable	The number of points in xTable and yTable

setData() [2/2]

template<size_t sizeTable>

bool qlibs::interp1::setData ( real_t(&) xTable[sizeTable], real_t(&) yTable[sizeTable] )

inline

Set the data for the 1D interpolation instance.

Parameters

[in]	xTable	An array of size sizeTable with the x points sorted in ascending order.
[in]	yTable	An array of size sizeTable with the y points.

setMethod()

bool interp1::setMethod ( const interp1Method m )

noexcept

Specify the interpolation method to use.

Parameters

[in]

m

The interpolation method.

Returns

true on success otherwise false.
