Re: [ferret_users]: how integrate in any directions?

Hi Xavier,
The script uses the SAMPLEXY function, which takes your x-y-z field and 
creates an x-z field, where now x is just an abstract axis, 1,2,3,4, ... 
sample points.  You can integrate the result of SAMPLEXY along the new 
abstract axis.  If you want to create a new axis with, say, distance 
from the starting point along the path, then you could put the result of 
samplexy on that axis before integrating.  Just to sketch how it would 
go, the commands would be something along these lines:


  !  see how vertical_section calls samplexy
  yes? go/help vertical_section.jnl 
  ! Define a variable containing the section, using SAMPLEXY
  yes? LET section_var = SAMPLEXY(my_var) 
  ! Use whatever technique you like to integrate it, i.e.
  yes? LET integrated_section = section_var[x=@DIN]

Or if you define a variable with the distance along the path at each 
sample point (with, of course, the correct units)

  yes? let xdistance =
  yes? define axis/x/units=meters   xdist = xdistance
  yes? let section_dist = section_var[gx=xdist@ASN]

  yes? let integrated_section = section_dist[x=@DIN]
