Hello and thanks in advance,
I have the following code that I wish to improve. Specifically, I want to make the surface contours appear and have a certain opaque color. I just can't figure out how to arrange the vectors so that I can create a surf plot. Any better method is much appreciated.
{vt1=zeros(51,2);
vv=zeros(51,51);
vt=0:0.02:1;
vt1(:,1)=transpose(vt);
vt1(:,2)=vt1(:,1);
zero=zeros(51,2);
mu=tand(2/3*40);
psi=0.33;
for i=1:1:51
vv(:,i)=vt(i);
mnm(i,1)=psi*vt(i)*(1-vt(i))^(0.95);
mnm(i,2)=-1*psi*vt(i)*(1-vt(i))^(0.95);
hnm(i,1)=mu*vt(i)*(1-vt(i))^(0.95);
hnm(i,2)=-mu*vt(i)*(1-vt(i))^(0.95);
hh(:,i)=transpose(linspace(hnm(i,2),hnm(i,1),51));
mmp(:,i)=psi.*((vv(:,i).^2.*(1-vv(:,i)).^(2*0.95))-((hh(:,i)/mu).^2)).^(0.5);
mmn=-1*mmp;
end
figure(4)
plot3(vt1,mnm,zero,'b')
hold on
plot3(vt1,zero,hnm,'r')
hold on
plot3(vv,mmp,hh,'g')
hold on
plot3(vv,mmn,hh,'g')
hold on}

hold on
% plot3(vv,mmp,hh,'g')
surf(real(vv),real(mmp),hh)
surf(real(vv),real(mmn),hh)
% plot3(vv,mmn,hh,'g')
plot3(vt1,mnm,zero,'b')
plot3(vt1,zero,hnm,'r')
shading interp
YOu need to initilaize the variables inside loop.
