plot3(A,r,v2)
老是有错,
A的范围如上,r大于0即可.

这个可以运行,就是数据大小要一致
A=0:0.1:5;
r=0:0.1:5;
B=90-A;
u=0.2;
m=70;
g=9.8;
v0=15;
h=2;
k=sqrt(sind(B)/cosd(B)*sind(B)/cosd(B)+1);
b=r*(1-k);
a=r*(sind(B)/cosd(B))/k;
v1=v0*v0+2*g*(h-b)-2*u*g*(sind(B)/cosd(B))*(h-b);
c=(m*v1/r+m*g*sind(A)-3*m*g*(2*m*cosd(A)+sind(A))/(1+4*m*m))/(exp(-2*u*A));
V2=6.*g.*r.*m.*(2.*m.*sind(A)-cosd(A))./(1+4*m*m)-c*exp(-2*u*A)/(m*u)-6*g*r*m*2*m/(1+4*m*m)+c*exp(-2*u*pi/2)/(m*u)+2*g*b+v1;
