Class ExponentialFilterResponseFunction

A typical exponential-falloff mode response filter function.

See description in Section 5.6.1 of Hesthaven/Warburton.

Instance Methods

Method Details

Construct the filter function.

The amplification factor of the lowest-order (constant) mode is always 1.

Parameters:

min_amplification - The amplification factor applied to the highest mode.
order - The order of the filter. This controls how fast (or slowly) the min_amplification is reached.
