Hi all,
Has anyone used the procedure ENVI_FX_DOIT?
I have copy the example from the ENVI Reference Guide pag 240 and it
keeps telling me:
Unknown Routine Name 'envi_fx_doit'
Since the data in my ENVI resources DVD are not the same as the
Reference Guide talk about I have used my own data.
Bellow I copy the procedure.
Does anyone know why the routine it is not recognise by ENVI.
Regards,
Jose
