Nettet4. des. 2013 · If I get rid of the .^2 in the 4th line, it does a linear fit perfectly. Perhaps my problem rests more in my lack of knowledge with least squares than with Matlab, but, either way, I'm stumped (advise if this should be moved to the math forum). Nettet2. des. 2024 · f (x) = a*x. because it will not fit correctly the data, it would be better to use linear function with an intercept value: f (x) = a*x + b. defined as such: def fun (x,a,b): return a * x + b. Basically, after running your example, you will obtain the best parameters (a the slope and b the intercept) for your linear function to fit your example ...

Line of Best Fit Definition (Illustrated Mathematics Dictionary)

NettetCurve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. [4] [5] Curve fitting can involve either interpolation , [6] [7] where an exact fit to the data is required, or smoothing , [8] [9] in which a "smooth" function is constructed that approximately fits the data.
