IGOR Pro

From Wikipedia, the free encyclopedia

IGOR Pro is a scientific data analysis software package that runs on Windows or Mac operating systems. It is produced by Wavemetrics Inc., and was originally aimed at time series analysis, but has since then evolved and covers other applications such as curve fitting and image processing. It comes with a comprehensive programming language with compiler, but many functions are also accessible through menus. IGOR Pro's strengths include its graphics capabilities, and the possibility of extending the built in functions with external operations XOP allowing data acquisition, manipulation and analysis features, communication with external devices and in principle any other task that can be programed in C or C++.
