tester_tabeller.xlsx Hi! I am trying to find alternatives of using gscatter function as I dont want to buy the machine learning tool box that can make it possible to use the gscatter function. Therefore, I searched a little and found that I could use the surf function. ...
But I have a predefined function f. I have to plot it against two different variables x and y . f is not a direct function of x and y.
surf(u,v,F); shadinginterp; however, in this way, matlab tells me '' 错误使用 surf (line 71) Z 必须为矩阵,不能是标量或向量。'' how can I use surf correctly? 0 Comments Sign in to comment. Answers (1) Vosson 18 Jan 2022
I use fsurf function and I would like to custmize function. The default of fsurf(...,"FaceColor","interp") is the interpolation on ZData. I want to interpolate by me own data. How could I do that? I know surf function can do the job, but when my gragh is large, I like the...
The code below displays a smooth function and my attempt to estimate it from random samples using nufftn(). The range and overall shape of the estimate comes out right on, but it's very noisy, becaue the random samples aren't uniform and therefore aren't great for estimating Fourier ...

Open in MATLAB Online Hello! I think mine is a question about how the function surfc() works. I have very recently discovered to my surprise an easy way to create the Edgeworth Box of microeconomics using surfc. Here is an example (with green curves and red curves...
In the above example, we use the peaks function to implement the graphics functions such as surf, mesh, and color, etc. here;, we use the mesh graphic function as shown. After that, we set the minimum limit of the xlim () function at 1, and at that same time, Matlab calculated the...
Open in MATLAB Online First, vectorizing will help: ThemeCopy F = 2 * x(1).^2 - x(2).^2; Second, you are confusing fplot, since it does not know what to do with a bivariate function. A solution is to use fsurf (or fmesh), and create ‘A’ as a function of two variab...
Open in MATLAB Online Ran in: The general approach would be to create a rectangular array first, and then use the cart2pol function to create it as a semicircular area. Example — ThemeCopy a = linspace(0, pi, 80); % Angle Vector r = linspace(0, 12, 24); % Radius Vector [A...
