Polynomial Fit for 2d arrays

[bmoyer]

I have a function that finds a polynomial fit of each pixel location through multiple images and it's taking a very long time to calculate (because of the hundreds of 1000s of pixel location it needs to iterate through). I would like to create a new function that works on all of the pixels in the images at once, but the subVI in the original function, "General Polynomial Fit.VI", makes a call to the lvanlys.dll, making this difficult to implement.

Any ideas?

Well you can you use linear algebra functions to a make line or a plane fit.
