extrema is a powerful visualization and data analysis tool that enables researchers to quickly distill their large, complex data sets into meaningful information. Its flexibility, sophistication, and power allow you to easily develop your own commands and create highly customized graphs.
With its roots at a particle physics laboratory (TRIUMF), extrema was designed first and foremost to be of the greatest practical use to researchers. The legacy of this design approach is a data analysis and visualization package that is both extremely powerful and easy-to-use. The average user can be doing productive work within minutes of first starting the program, yet its features and functionality are nearly inexhaustible!
Earlier versions of extrema have been released by TRIUMF under the product name physica. The switch from Physica to extrema is effortless, and there are many new features to be gained.
