【MATLAB函数quiver()】颤振图将速度矢量表示为箭头, 在点(X, Y)处具有分量(U, V)。
句法
quiver(U, V, U, V)quiver(X, Y)quiver(..., scale)quiver(..., LineSpec)quiver(..., LineSpec, 'filled')h = quiver(...)例子
z=x^2+y^2-5sin?(xy)|x|≤2, |y|≤2.r=-2: .2:2;
[X, Y]= meshgrid (r, r);
Z=X.^2- 5*sin(X.*Y)+Y.^2;
[dx, dy]=gradient (Z, .2, .2);
