The function returns the interpolated value (a scalar) of \(logC(\delta)\) based on its results on selected knots, given input vector of \(\delta\).
logCdelta(delta, deltaknot, lCknot)a scalar of the input value of \(\delta\).
a vector of the knots for \(\delta\). It should be selected before conduct the sampling.
a vector of the values \(logC(\delta)\) on selected knots, coming from the function logCknot.
A sequence of the values, \(logC(\delta)\) on selected knots.
