拟合Y值对不上容易犯的错误。其错误的原因是，x、y向量组的方向不一致，即x=[x1;x2;x3;x4]的是4×8的行向量，而y向量组是1×8的行向量，而lsqcurvefit要求x、y向量组为列向量，所以题主可以做如下调整即可。x=[x1', x2',x3',x4']; %把行向量转换为列向量 y=[0.2828 0.422 0.4...
This MATLAB function returns a logical array with elements set to logical 1 (true) where the real-world values of A and B are not equal, when A or B is a fi object.
https://matlab.fandom.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F But if you are insisted to way out, you may consider difference between the numbers as allowable tolerance (error) and use > or < logical comparision in the "if statement". ...

MATLAB FAQ: Why is 0.3 - 0.2 - 0.1 (or similar) not equal to zero? 1 Comment Ned Gulley on 20 Jan 2011 Hi Matt: Yes, this is an obvious one to get the ball rolling. By the way, I changed the formatting of your answer slightly to make the link a little clearer. Sign in ...

Open in MATLAB Online I am trying to use the lsqcurvefit function to fit a sine wave to a data set, however i get the following error: Functionvalue and YDATA sizes are not equal. when running the following code: ThemeCopy A = 0.3; ...
Use the geometry in lshapeg. For more information about this syntax, see Parameterized Function for 2-D Geometry Creation. Get g = @lshapeg; pdegplot(g,'EdgeLabels','on') axis equal ylim([-1.1,1.1]) Set zero Dirichlet boundary conditions using the lshapeb function. Get b = @lsh...
g = @squareg; pdegplot(g,'EdgeLabels','on') ylim([-1.1,1.1]) axis equal Set Dirichlet boundary conditions u=0 on all edges. The squareb1 function specifies these boundary conditions. b = @squareb1; Generate a relatively fine mesh. [p,e,t] = initmesh(g,'Hmax',0.02); Set the in...
