n. [scientific computation] In solving partial differential equations by
|
|
|
|
|
finite difference and similar methods, wiggles are sawtooth
|
|
|
|
|
(up-down-up-down) oscillations at the shortest wavelength representable on
|
|
|
|
|
the grid. If an algorithm is unstable, this is often the most unstable
|
|
|
|
|
waveform, so it grows to dominate the solution. Alternatively, stable
|
|
|
|
|
(though inaccurate) wiggles can be generated near a discontinuity by a Gibbs
|
|
|
|
|
phenomenon.
