| Post subject: | optimization functions for VBA |
I am trying to find an multivariate constrained optimization algorithm that I can use in VBA. I found the ALGLIB free package and downloaded it. It looks like "minlm" might be what I'm looking for, but I can't find any examples of its use and I'm stumped just looking at the source code. Does anyone have an example of use in VBA (or VB6) ? |

ALGLIB for VBA is quite old (many years old), misses most functionality present in modern ALGLIB versions. As far as I remember, it misses constrained LM functionality. Only unconstrained fits are performed. |

Hey, you can use ALGLIB in Excel by compiling a dll. I described a possible way in this post: http://forum.alglib.net/viewtopic.php?f=2&t=2165 Best regards. |

And I'm hoping that spline1d is the right tool to interpolate smoothly between the points while ensuring that queries for points where data has been provided return exactly the data from the map. I will also need to get values for x=0 to x=10, and x=245 to |
