hi, according to this code i would like to plot my output(qult)versus these values CS,F .please help me/
code :
B=1000;L=2000;Df=200;Sc=1.1;Sq=1.1;Sgama=.8;dgama=1;dc=1.08;
nsamples=10000;
for i=1:nsamples
CS=C(1,i);
WS=G(1,i);
F=fi(1,i);
Nq=tan((pi/4)+(pi*F/360))*tan((pi/4)+(pi*F/360))*2.718^(pi*tan(F*pi/180));
Nc=(Nq-1)*cot(F*pi/180);
Ngama=2*(Nq+1)*tan(F*pi/180);
dq=1+(0.4)*(tan(F*pi/180))*(1-sin(F*pi/180))^2;
qult(i)=(CS*Nc*Sc*dc)+(384*Nq*Sq*dq)+(980*Ngama*Sgama*dgama);
end
qult is a function of those 3variables CS,WS,F.

surf( C(1,1:nsamples), fi(1,1:nsamples), qult );
Note: for efficiency, before your loop, you should do
qult = zeros(1,nsamples);

Your posted code assumes that C and G and fi all exist before getting to that line. Only you know how those variables need to be initialized.

UJJWAL had the good point that you should use plot3() instead of surf() for this situation.
But you still need to initialize C and G and fi.
