Hi all

i need to realize a 3d plot for displaying 3 connected quantities.

for i=1:length(i_ed)   
    for j=1:length(x)
    if K1(i,j)>0
   psl(i,j)=(70*(W_end_t(i)/Sr(i))*K1(i,j)*K2(i)*K3*acg(i))*1000;%N/m^2 RES22 (61)
    end
    end
end
plot3(L_end,x,psl)
xlabel('L')
ylabel('x')
zlabel('Psl')
hold on

where L_end has length(i_ed) elements. For better understanding the problem, x/L_end varies between very small values to 1. My goal it is to graph in the same 3d plot many curves as L_end length.

Thank you for the help!

You must be getting an error message. What does it say (all the red text)?

Check that your inputs are what plot3 expects.

plot3(X,Y,Z) plots coordinates in 3-D space.

To plot a set of coordinates connected by line segments, specify X, Y, and Z as vectors of the same length.
To plot multiple sets of coordinates on the same set of axes, specify at least one of X, Y, or Z as a matrix and the others as vectors.
