hi all,
according to this code i would like to plot my output(qult)versus these values CS,WS,F .IS there anyway,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.

Sorry, 3 dimensions is the maximum for plotting, but you have four dimensions. You would have to represent one of your dimensions as color or transparency or point-size or point-shape. scatter3() is your best bet.

thank you for your help,would you please explain me more on using scatter3 command.?//

pointsize = 8;
scatter3(CS, WS, F, pointsize, qult)
This would create an sphere at each CS(i), WS(i), F(i) location, with the sphere being colored according to the value of qult(i)
