MATLAB: How i can generate random points inside a cube

cuberandom points

i want to generate rondom points inside a cube.

Best Answer

You can use rand()

 Z = rand(10,10,10);

The above gives you the unit cube. You can translate this and scale the side length:

 Z = 2+(4-2)*rand(10,10,10);

Replace

   [dx,dy]=odehandle; %does not work!

with

   temp = arrayfun(@(X, Y) odehandle([],[X,Y]), x, y, 'uniform', 0);
   dx = cellfun(@(C) C(1), temp);
   dy = cellfun(@(C) C(2), temp);

This is for the special case that the ODE is a function of two variables and the first derivatives apear as the first two elements of the output vector.

The 3D equivalent would be something like,

function plot_vectorfield(odehandle)
   [x, y, z]=meshgrid(-10:1:10, -10:1:10, -10:1:10);
   temp = arrayfun(@(X, Y, Z) odehandle([],[X,Y,Z]), x, y, z, 'uniform', 0);
   dx = cellfun(@(C) C(1), temp);
   dy = cellfun(@(C) C(2), temp);
   dz = cellfun(@(C) C(3), temp);
   quiver3(x, y, z, dx, dy, dz);
end
