/**
|
|
* This function allows to obtain the value of a given calibration parameter for
|
|
* frequencies outside the calibration points. It works by searching the two
|
|
* calibration points containing the target frequency and then by linearly
|
|
* interpolating the calibration parameter among these two points.
|
|
* @param freq: target frequency for which a calibration value has to be
|
|
* computed.
|
|
* @param calPoints: pointer to the vector containing the frequencies of the
|
|
* calibration points.
|
|
* @param param: pointer to the vector containing the values for the calibration
|
|
* parameter, it must have the same length of the one containing the frequencies
|
|
* of calibration points.
|
|
* @param elems: number of elements of both the vectors for calibration parameter
|
|
* and frequencies.
|
|
* @return value for the calibration parameter at the given frequency point.
