IGOR Pro is an extraordinarily powerful and extensible graphing, data analysis, and programming tool for scientists and engineers.

• Journal-quality scientific graphs
• 3D and volume visualization
• Flexible image display
• Handles large data sets very quickly
• Extensive scientific and engineering data analysis
• Curve fitting, peak fitting
• Signal processing
• Image processing and image analysis
• Special support for evenly spaced data
• Completely programmable and customizable

Academic and Student pricings are available, see this page for more information.

• Macintosh: Added a workaround for Apple breaking FSResolveAliasFile for Finder aliases in OS X 10.10 Yosemite. This prevented Finder aliases used to activate XOPs from working as well as preventing other uses of Finder aliases.
• Macintosh: IgorInfo(3) now returns the correct operating system version for OS X 10.10 Yosemite.
• Corrected V_Value normalization result for Cos3 and Cos4 methods of the WindowFunction. operation.
• The Data Browser's Browse Experiment feature works again, fixing a bug introduced in version 6.35.
• SetAxis axisName, NaN,NaN no longer crashes.
• Fixed CurveFit bug: if a matrix data wave had a subrange on it, the compiled version didn't properly set the subrange for X waves that had no subrange (and therefore should have gotten the appropriate subrange from the Y matrix).
• Fixed crash when doing ODR fit to data with NaNs and an explicit destination wave.
• Fixed multithreading problem in ImageBoundaryToMask.
• Fixed thread-safeness of StructPut and StructGet with wave[pointNum].
• If you wrote an Igor text file for a wave that contained a wave note longer than about 400 characters, you got an error when you tried to load the Igor Text file back into Igor. (This bug was introduced in Igor 6.35 and fixed in 6.36.)
• AreaXY no longer computes slightly incorrect results when the X values are decreasing, fixing a bug introduced in Igor 6.35.
