Revision as of 04:53, 12 October 2008
The most frequent question encountered from a new user is: "Does Madagascar do [some needed process]?" The first level of classification is therefore by types of procedures. The classifications below try to follow the user's workflow:
- What is the function to read such type of input data file ?
- Is there a function to perform a Fourier transform, a causal integration ?
- How can I display 2-D data ?
All program names below should be prefixed with "sf".
