Madagascar is a software package for multidimensional data analysis and reproducible computational experiments.

The work on the package (previously named RSF) was started by Sergey Fomel in 2003.

[3] While being written mostly from scratch, Madagascar borrows ideas from the design of SEPlib, an open-source package maintained by Bob Clapp at the Stanford Exploration Project (SEP).

Most important contributions came from Rob Clayton, Jon Claerbout, Dave Hale, Stew Levin, Rick Ottolini, Joe Dellinger, Steve Cole, Dave Nichols, Martin Karrenbach, Biondo Biondi, and Bob Clapp.

Main contributors to SU included Einar Kjartansson, Shuki Ronen, Jack Cohen, Chris Liner, Dave Hale, and John Stockwell.
