hi
I want to plot3 some points with X,Y,Z coordinates from different known domain. for example, X= 1:0.5:10 Y=0:0.2:25 z=0:0.1:4 . I want to set all ponits witch have (X,Y,Z)'s coordinats from all possible member of domains one by one then use plot3 or scatter3 the point (all of them...not random or specific one). I want to use uniform distribution.

X = 1:0.5:10; Y = 0:0.2:25; Z = 0:0.1:4;
[x, y, z] = ndgrid(X, Y, Z);
pointsize = 15;
scatter3(x(:), y(:), z(:), pointsize);

hi Walter,
thank you. It works.
Now , how could it be possible to make a struct like Points.X -Points.Y-Point.Z? where each point has its own cordinations inside the struct. i am asking this because X Y Z have different dimention.

Points.X = X;
Points.Y = Y;
Points.Z = Z;
??
That would be the non-gridded points without repetitions. If you want the repeated points then there would be equal numbers and you would use
Points.X = x(:);
Points.Y = y(:);
Points.Z = z(:);
or
Points.X = x;
Points.Y = y;
Points.Z = z;
if you want the 3D grids.
