Newton, MA (PressExposure) September 20, 2011 -- Free Software Adds Cubic Spline and Linear Interpolation functions to Microsoft Excel
SRS1 Software, LLC announces the availability of SRS1 Cubic Spline for Excel 2.0 for Windows. SRS1 Cubic Spline for Excel is free software that adds cubic spline and linear interpolation functions to Microsoft Excel. It is compatible with Excel 2007 and later versions of Excel.
Spreadsheets are the most common tool that engineers, scientists and financial professionals use for analyzing data. Spreadsheets are simple to use, flexible, and powerful. Yet despite these strengths, spreadsheets do not have the analytical capabilities needed by some users. Interpolation is a good example of this. Performing cubic spline interpolation in a spreadsheet can be very difficult. Users are usually forced to export their data to some other data analysis software in order to perform the interpolation. After that, they need to manually import the results back into their spreadsheet.
SRS1 Cubic Spline for Excel is a free add-in that helps resolve this problem. It adds cubic spline and linear interpolation functions to Microsoft Excel. It takes no time to learn, because the added functions work the same way that existing Excel functions work. The new cubic spline and linear interpolation functions are also robust. They can accept input source data in any order, and at any spacing intervals.
For more advanced curve fitting and data analysis in Excel, a trial version of Data Curve Fit Creator Add-in software is also included in the download for SRS1 Cubic Spline for Excel.
