I am desperately trying to get my head around the Bspline function and associated functions like Spline2 but the help files leave allot to the imagination. I need a bit of a demo. Anyone got a worksheet (that would work in MCP3) that I can look at to get an idea of how the functions work specifically in terms of plotting data?
This is basically straight from the help files, but boiled down some. And the key part to make it useful is fitting the b-spline with a cubic so we can pull values at any point.
Weighting just gives more weight to some points as opposed to others, which will affect the fit accordingly. Other than this example I never use it. You likely don't need it either. You just need to delete the 'w' in the b= equation to ignore it.
