Hi ... I have tried to solve the following problem, but I failed. Can you help me?
Use MATLAB to generate and plot a three-dimensional grid of (6 X 8 X 10) resolution for a (8m X 6m X 5m) rectangular body.
The following is my code and it's not working..!! Help
clear, clc
W=8; % Width
H=6; % Hight
D=5; % Depth
i=6; % Nods number (x-direction)
j=8; % Nods number (y-direction)
k=5; % Nods number (z-direction)
x=linspace(0,W,i); % x
y=linspace(0,H,j); % y
z=linspace(0,D,k); % z
[x,y,z]=meshgrid(x,y,z);
plot3(x,y,z,'ok')

Try
[X,Y,Z] = meshgrid(x,y,z);
plot3(X(:),Y(:),Z(:),'ok')

I’m not sure what all you wanted to do. Is this what you were looking for?
clear
clc
W=8; % Width
H=6; % Hight
D=5; % Depth
i=6; % Nods number (x-direction)
j=8; % Nods number (y-direction)
k=5; % Nods number (z-direction)
x=linspace(0,W,10); % x
y=linspace(0,H,10); % y
z=linspace(0,D,10); % z
plot3(x,y,z,'ok')
xlabel('x label')
ylabel('y label')
zlabel('z label')

No, your answer is wrong... Thanks anyway.
The values of i, j and k are not equal and not equal to 10. Focus on my code please.
