Igor Pro is an interactive software environment for experimentation with scientific and engineering data and for the production of publication-quality graphs and page layouts. Igor has been used by tens of thousands of technical professionals since its introduction in 1989. Here are a few highlights of the newly released Igor Pro 8.

Produces and exports high-resolution, journal quality scientific graphs in EPS and PDF
Handles large data sets very quickly
Includes a wide range of capabilities for scientific and engineering analysis and simulation
Contains a built-in programming environment that makes it easy to automate applications and extend internal tools
Completely programmable via a built-in programming environment and can be extended by external code (XOPs) written in C
Igor Pro has special support for time-series or other evenly-spaced data
Includes extensive image processing tools for image filtering, manipulation and graphing
Runs on Macintosh and Windows computers; Igor Pro 8 data files are cross-platform compatible
Imports data in many formats and can acquire data from hardware devices
Uses unicode to support foreign languages and mathematical symbols
Active user-to-user support and collaboration forum
Responsive, user-acclaimed technical support
Includes Igor Filter Design Laboratory for interactive design of FIR and IIR digital filters

Igor Pro is an excellent tool for:

Graphics Creation - Igor Pro is first and foremost a publication quality scientific and engineering graphics program, capable of creating visually stunning 3D graphics as well as 2D graphs
Data Access - Scientists and engineers encounter many data formats. Igor Pro provides a variety of import, storage and export capabilities that can handle almost any requirement.
Data Storage - Unlike spreadsheet programs, Igor Pro's data objects won't clutter up your screen. Efficiently organize your data into a hierarchy, just like you would organize files in a hierarchy of folders on your hard drive!
Data Manipulation & Math - Igor Pro provides an extensive library of math and data manipulation routines and Igor's array-oriented arithmetic make complex operations a snap.
Image Processing - Igor Pro contains a full set of operations and functions for scientific image analysis applications.
Data Analysis - Igor provides many analysis capabilities, including curve fitting, peak analysis, signal processing and statistics.
Analysis of Function - Igor includes several operations that work on functions rather than discrete data points, including: plotting of functions, differential equations, numerical integration of functions, root finding and optimization.
