數值雙積分函數處理

-2

power = 2; 


sigma=0.1; 

a = 1 /(sigma*sqrt(2*pi)); 
c= (sigma^2)*2; 

syms x y 

f = exp(-(x.^power)./c); 

dfdx = diff(f,x); 

c1 = diff(dfdx,x); 



f = exp(-(y.^power)./c); 

dfdy = diff(f,y); 

c2 = diff(dfdy,y); 



meancurvature = (c1 + c2)./ 2; 

    gaussiancuravture =(c1 .* c2); 



    mean_curv = integral2(meancurvature, -Inf,+Inf, -Inf, +Inf) 
    gauss_curv = integral2(gaussiancurvature, -Inf,+Inf, -Inf, +Inf)

我在我有限的知識MATLAB想盡一切和谷歌搜索來尋找答案隨附的錯誤了：數值雙積分函數處理

使用integral2

第一個輸入參數誤差必須是一個功能句柄。
