WebJan 15, 2015 · You must come up with a function that you believe is capable of fitting the data, then use Solver to minimize the RSS deviations between the function and the data you have. For example, if you believe the function Ax^2 + By^2 + Cxy + Dx + Ey + G = 0 WebAug 7, 2014 · If you have the Curve Fitting Toolbox, it's easy to fit a surface to 3 x,y,z vectors using the fit function. Here's some example code that fits a polynomial surface to random points. You can define your own fitting function if you like or check out the other fitTypes they have for surfaces. Here's the documentation for fit.

WebSorted by: 11 Spline interpolation on for 3+ dimensions can be done using scipy.interpolate.Rbf as your described. For plotting purposes you can use a smaller resolution (1000 points is a good rule of thumb), and when you want to evaluate your spline, you can interpolate on much greater than 132000 points without problem (see … WebTo do least square fit, you simply follow these three steps. 1.) Define the least square error function, for example, you could do e(A, B, C) = ∑ (Ax + By + C − z)2 2.) Assuming you have no special constraint you want on A, B and C, so it is simply an unconstrained optimization problem. You differentiate the error function and set zero. todd borowski south milwaukee
