- 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.
Very helpful, many thanks!
Very helpful. Is it possible to get the mathematical explanation behind the method
Nice job, Shen.
Thanks for the tutorial!
兄弟，怎么拟合三维曲线啊？他出来的都是曲面。不会弄
Thanks!
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
Hi Mr Shen, please how to fit multiple graphs 2D
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.
Hello Dr. Shen. Hope you are doing well 😀Lei
Haha, what a surprise!
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
