Some IDL documentation.
IDL Reference Card
This is a terse list of important IDL features formatted like the Emacs
reference card (but for A4 paper):
PostScript version (100 kB);
PDF version (110kB).
Introduction to IDL
Here you find the
PDF transparencies (created with
LaTeX plus hyperref and pdfscreen) of an
introductory talk to IDL which I gave in the
in Applied Maths at Newcastle University.
A printable version is also available.
Be however warned that these slides will probably not be very useful
on their own.
You can have a tour de force through the demos by `sourcing' the
two files intro.jou and
intro2.jou (you need to start a new IDL
session for intro2.jou or you will get error messages):
Here is the output of the volume rendering of fff
and there is also a VRML file created from the
data (and, just for fun, you can use
Vrml2pov to convert
the VRML file into a
Povray scene description and raytrace
it; here is the result).
Some files used in the introduction are available here
The following are used, but never explicitly listed in the slides
- linspace.pro --- create an equidistant
sequence of numbers like
- spread.pro --- duplicate array elements
like the Fortran 90 spread function
- contourfill.pro --- essentially an
abbreviation for `contour, /FILL, NLEVEL=60' (requires
- psa.pro --- switch output to PostScript
- pse.pro --- switch output back to whatever it
was before the call to psa.pro
- ps_fonts.pro --- Use PostScript fonts
(for PostScript output); needed by psa.pro
- rk.pro --- 3rd oder Runge-Kutta
- xder_6th_1d.pro --- defines the
function xder for 1-d and periodic boundary conditions
- xder2_6th_1d.pro --- defines the
function xder2 (second derivative) for 1-d and periodic
