Application Details

• Description : IDL, short for Interactive Data Language, is a programming language used for data analysis. It is popular in particular areas of science, such as astronomy, atmospheric physics and medical imaging. IDL shares a common syntax with PV-Wave and originated from the same codebase, though the languages have subsequently diverged in detail.
• Versions : 8.4
• Module names : idl/8.4
• License: University of Hull Engineering department, restricted by physics department

Usage Examples

IDL Programs

Below is an example of a very basic IDL program called helloworld.pro

; helloworld.pro
pro helloworld,what
  print,'HELLO ',what
end

And the corresponding main.pro program

; main.pro
