MATLAB curve fitting for 1D, 2D and 3D
I use three examples to show the procedures for MATLAB curve fitting.
Case 1: 1-dimensional distribution probability curve fitting.
Case 2: 2-dimensional stress-strain curve fitting.
Case 3: 3-dimensional fracture surface fitting.

I have dialy one year temperature data. I want to investigate kelvin wave. The kelvin wave investigation is original temperature minus curve fitting temperature . How can I write a code for sinusoidal curve fitting of this temperature data? the data is 3 D
Thanks!
兄弟,怎么拟合三维曲线啊?他出来的都是曲面。不会弄
Thanks for the tutorial!
Nice job, Shen.
Hi Mr Shen, please how to fit multiple graphs 2D
Very helpful. Is it possible to get the mathematical explanation behind the method
Hello Dr. Shen. Hope you are doing well 😀Lei
Haha, what a surprise!
Very helpful, many thanks!
thnks for sharing... how to import a text file data to this tool-fit.
I created new variables first, then copy and paste the data. You can also import a txt file data into a workspace first, then select the corresponding variables.
@@fuhuishen358 my data is made of 205 rows in cartesian coordinates (xyz). this coordinates indicate a curvature of a layer. So, i want to calculate radius of this curvature systematically.. for this layer, hyperbolic paraboloid is suitable. hyperbolic paraboloid has an equation. z=y^2/a^2 -x^2/b^2. i want to fit my data to this equation. this is my problem
Hi Shen. I have a quick question. I am a little bit confused between curve fitting and parameter estimations. Does curve fitting toolbox also recognize the parameters?
Yes, in the curve fitting toolbox, the optimized parameters of pre-defined equations will be provided.
