Waveform Distortion Data for Bivariate Interpolation
Description
akima is a list with components x, y and z which
represents a smooth surface of z values at selected points
irregularly distributed in the x-y plane.
The data was taken from a study of waveform distortion in
electronic circuits, described in:
