Category:Isis / Slang

This page is being discussed.

The [Interactive Spectral Interpretation System (ISIS)] was developed at MIT for the analysis of X-ray spectra.

Note that this page was just copy-pasted from the old wiki. This is only a short list of instructions that will be available. I do not think that a full list of all instructions should go here for the new wiki, I'm trying to find another solution for that (Matthias: What about looking at the content of the category below?) In the end, I think only the instructions to get isis running and first steps should be here (Matthias: I disagree because category pages (like this) are not considered during searches! That's why I have created pages with the "ISIS history file" and "ISISscripts" separately). I will move all the advanced stuff like defining models, timing tools, etc. somewhere else.

S-Lang tips & tricks

• S-Lang modules (function packages)
• writing helps for functions
• functions within structures
• function nesting
• self-value-management
• changing qualifiers before passing them on
• speed up code
  • iterating over an array - three different for-loops
  • ternary operator ?:
  • profile - Run-time profiler: Analyses (nested) function run-times
• passing information to a fit function via metadata
• References to variables
• Name of the calling function
