Since I can only give one value back at a time to Excel


You don't say how you are communicating between Excel and C#, but it is possible to return an array to Excel.

in VBA: Range("XLRange").Value = CSArray

Where CSArray is any array, and XLRange is a range address or range name with the same dimensions.

Student - I haven't used Excel DNA, so I can't give any specifics, but I'm sure it's possible to return three values to Excel without runing the Alglib function three times. If your Excel routine is written as a sub you should be able to just write the values to the spreadsheet. If it is written as a user defined function you will need to return the values as a variant array, which can be entered as an array function, or you could use the Index function to access the values in the array.
