[ExcelDna] ExcelDna tutorial

[Ed Parcell]

Hello,

I have written a short tutorial on using ExcelDna to expose numerical
algorithms to Excel from the AlgLib numerical library. I think it
might be interesting to people looking for a simple how-to guide to
getting started with ExcelDna, or to those looking for high-quality
numerical libraries to use in Excel.

The tutorial is available on my blog at
http://edparcell.posterous.com/tutorial-numerical-analysis-in-excel-using-c

Any feedback gratefully received.

Best regards,
Ed.

Nice tutorial Ed. It's awesome to see all these great developers
helping others get started with ExcelDna. Also, I wasn't aware of
AlgLib up until now... I'll be adding that to my toolbox!

Hi Chris.

Thanks very much. I hope it helps the project and others who want to
use it. I will probably be writing more on ExcelDna in the future, so
I'll make sure to let this group know when I do.

Yup, AlgLib seems very cool. It's nice to have numerical routines in a
modern language so you can see what's going on inside, and make tweaks
if necessary.

Best regards,
Ed.

Hi Nick,

* Did other functions you are exporting work OK?

* What have you tried for the random numbers, what goes wrong?

* Do you need to mark your functions as 'Volatile' to make then
recalculate every time - like this:
[ExcelFunction(IsVolatile=true)]
public static double GetRandom() {....}

Regards,
Govert
