How to generate and plot a 3D structured mesh in MATLAB?

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')

Thank you... Can you connect all nods with crossed lines to look like a grid?

I added NaN at the end of each dimension to break up line

W=8;    % Width
H=6;    % Hight
D=5;    % Depth
j=6;    % Nods number (x-direction) (columns)
k=8;    % Nods number (y-direction) (3d dimension)
i=5;   % Nods number (z-direction)  (rows)
x = [linspace(0,W,j) nan]; % x
y = [linspace(0,H,k) nan]; % y
z = [linspace(0,D,i) nan]; % z
[X1,Y1,Z1] = ndgrid(x,y,z);
[Y2,X2,Z2] = ndgrid(y,x,z);
[Z3,X3,Y3] = ndgrid(z,x,y);

plot3(X1(:),Y1(:),Z1(:),'o-k')      % X lines
hold on
plot3(X2(:),Y2(:),Z2(:),'-k')       % Y lines
plot3(X3(:),Y3(:),Z3(:),'-k')       % Z lines
hold off

A very simple question have such an advanced answer. Thank you very much for your time.

If you don't mind, can you be my first friend in this community... I'm new to this comunity and this was my first question.

I don't know how to invite you.

of course!

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.
