One-dimensional linear interpolation. Returns the one-dimensional piecewise linear interpolant to a function with given discrete data points ( xp, fp ), evaluated at x. The x-coordinates at which to evaluate the interpolated values. The x-coordinates of the data points, must be increasing if argument period is not specified.
