Calculating frequency attenuation gradient.

 
Synopsis
        sffagrad < in.rsf > out.rsf grad=y lperc=65. hperc=85. freq= type=

 
Parameters
       
 
float freq=
Frequency corresponding to energy ratio, valid when type=ratio
 
bool grad=y [y/n]
If y, output attenuation gradient; if n, output absorption factor
 
float hperc=85.
High percentage of total energy
 
float lperc=65.
Low percentage of total energy
 
string type=
[low,full,ratio,attenuation] attribute type, the default is attenuation
