Linear/parabolic radon transform frequency domain implementation

 
Synopsis
        sfmyradon2 < in.rsf > out.rsf adj=y inv=n np= dp= p0= niter=100 eps=0.01 nx= ox= dx= parab=n x0=1. invmode=
Also referred to as high-resolution radon transform
Note: I borrowed a lot from /system/seismic/radon+Mradon.c. The distinction:
I am using FFTW because I am inexperienced in invoking kiss_fft.

 
Parameters
       
 
bool adj=y [y/n]
if y, perform adjoint operation
 
float dp=
p sampling (if adj=y)
 
float dx=
sampling interval in x
 
float eps=0.01
regularization parameter
 
bool inv=n [y/n]
if y, perform inverse operation
 
string invmode=
inverse method: 'ls' if least-squares; 'toeplitz' if use FFT
 
int niter=100
number of CGLS iterations
 
int np=
number of p values (if adj=y)
 
int nx=
number of offsets (if adj=n)
 
float ox=
x origin
 
float p0=
p origin (if adj=y)
 
bool parab=n [y/n]
if y, parabolic Radon transform
 
float x0=1.
reference offset
