i want to draw 10 lines from x =0 till x=10 in 3d i tried but i wouldnt get my result any thoughts??

x=0:1:10;
y=0:1:10;
z=0:1:10;
for j=0:1:10
for i=0:1:10
    x=x+i;
end
plot3(x,y,z)
end

Answer 1

[sixwwwwww]

do need something like this:

x = 1:10;
y = 1:10;
for i = 1:10
    plot3(x, y, x + i), hold on
end

Is it correct?

better than mine thats for sure but i want 10 lines parallel to the y axis only not y=x but that is a very good strategy I never though I could put 'i' in the 3dplot

[sixwwwwww]

for lines along parallel to y-axis you can do as follow:

x = ones(1, 10);
y = 1:10;
for i = 0:9
    plot3(x + i, y, x), hold on
end
xlabel('x'), ylabel('y'), zlabel('z')

Is it what you need?

it is almost perfect but i want it with z=0 i tried to put z=0 in the plot 3d i couldnt because in this case the interval of z and x wont be the same so what should i do??

[sixwwwwww]

you can plot at z = 0 as follow:

x = ones(1, 10);
y = 1:10;
z = zeros(1, 10);
for i = 0:9
    plot3(x + i, y, z), hold on
end
xlabel('x'), ylabel('y'), zlabel('z')

Add

hold on

after the plot3()

[abed]

i still get the same figure
