Excel and Mathematica?
MathGroupers: Do any of you know of work linking the Excel spreadsheet program and Mathematica - both under Windows on PC's? I have had a question from some researchers who want to be able to enter data into a spreadsheet - because that is what their people want to do - and then do nonlinear curve fitting to the data in a very transparent way. Right now there is no MathLink for the PC, so that is not possible. Is the only way to do this to save the Excel data into a file, then read the file into a Mathematica notebook, do the nonlinear fitting there and then the graphics? Has anyone done anything like this? What about on a Mac with or without MathLink? Are there any nonlinear curve fitting programs better or different than the ones shipped with Mathematica or on MathSource? Thanks. Steve Christensen
