Synopsis

interpol_data_lin_t<long, 2> interpolate_on_segment (double x, double x_min, double delta_x, long imax)

Fit the two closest points for x on [x_min, x_max], with a linear weight w

Parameters

• x : the point
• i_max : maximum index
• x_min : the window starts. It ends at x_min + i_max* delta_x
• delta_x Throws if x is not in the window
