y=@(x)4*a*sqrt(1-(c/a)^2*sin(x).^2);这就定义了这样的一个以x为自变量的函数y，但是与用function来定义的函数不同，它在matlab里没有函数名，并且只存在于内存中（关掉matlab后就被删除了）。之后直接积分就可以 true=quad(y,0,2*pi,1e-8);你用这个y='4*a*sqrt(1-(c/a)^2...
[Q,fcnt] = quadv(...)returns the number of function evaluations. The list below contains information to help you determine which quadrature function in MATLAB®to use: Thequadfunction might be most efficient for low accuracies with nonsmooth integrands. Thequadlfunction might be more efficient...

This function is an adaptation of Matlab's "quad" function to return the cumulative integration of an analytical function. e.g. compute integral: I(t) = int(0..t)[1/(tau^3 - 2*tau - 5) d_tau] for t=0..3 [I, t] = cumquad(@(tau) 1./(tau.^3-2*tau-5), 0, 3); ...
ThesubQuadfunction enables refinement of quadrangulated data. The quadrilateral faces defined by the patch format data F (faces) and V (vertices). Each face is split n times using the specified split method (splitMethod). The user may request the following outputs: The new faces: Fs The ...
