如何在Matlab中修复嵌套函数？

Question

% calculate the area of the circle
function a_circle = area(r)
a_circle=pi*r^2;
end

%calculate the volume of the cone
function v = vol(r,h)
v=0.333*area(r)*h;
end

在上面的代码中，表明 vol（r，h）未使用。如何解决此错误？

Answer 1

在area(r)内定义vol(r, h)：

%calculate the volume of the cone
function v = vol(r,h)
   % calculate the area of the circle
    function a_circle = area(r)
       a_circle=pi*r^2;
    end

    v=0.333*area(r)*h;
end
