matlab三维图求解答
c=0.785
Vif=c*pi*sqrt(3)/8
a=30
b=solve('tan(a)=3*sqrt(2)*tan(b)')
d=solve('tan(a)=6*tan(d)')
Vsf=(1+3*cos(a)/cos(b))*c*sqrt(3)*pi/24
Vcf=c*3*sqrt(3)*pi*cos(a)/(17*cos(d))
for m=1:30
for n=1:30
if m/2==0 & n/2==0
Vi=(2*(m-1)*(n-1)+2)/(2*m*n+m+n)
Vs=3*(m+n-4)/(2*m*n+m+n)
Vc=8/(2*m*n+m+n)
Vf=Vi*Vif+Vs*Vsf+Vc*Vcf
else
Vi=2*(m-1)*(n-1)/(2*m*n+m+n)
Vs=3*(m+n-2)/(2*m*n+m+n)
Vc=4/(2*m*n+m+n)
Vf=Vi*Vif+Vs*Vsf+Vc*Vcf
end
end

我用这个求出所有M,n对应的Vf值之后,如何做出M,N,Vf之间的网格图
急用》.
