using the unix 'at' command with IDL 1140 0
Started by Deleted User
I was able to piece together an IDL program that makes some jpeg images I need. It works great when I call it from the command line (i.e., I type 'idl makejpegplots.pro').
The problem is I need to set the program to run at some point in the future, so I thought I'd use the handy unix 'at' command.&160; For example, I can say:
echo "idl makejpegplots.pro" | at now 2 minutes"
I run many of my scripts this way instead of using a cron.
At the given time, I know the code runs, b...

Problem with surface command and/or direct graphics 1154 0
Started by Deleted User
Hi,
&160;
The problem I am currently having is that when I use the Surface command the image that I get is not correct. For some strange reason IDL seems to be confused and does not plot the surface correctly. The same problem occurs also when I use the iSurface tool in vector graphics mode.
The surface that I want to plot is:
x=sqrt(r^2a^2) cos(phi)sin(theta)
y=sqrt(r^2a^2) sin(phi)sin(theta)
z=r cos(theta)
for r=8 and a=6. I can't really understand why the image is not correct in the...
