I have a complex function whos output values I want to use in my spreadsheet. I was wondering if there's any way to use Gnumeric spreadsheet to send variables to my octave program to have the octave program solve the function (the function requires solving of simultaneous equations used in a numerical solver to return values).

The tricky part of the simultaneous equations is that the coefficient matrices can't really be generated in gnumeric or any other spreadsheets...

Has anyone ever heard of this, or do I just have to make my program handle everything?
