Thread Subject: initialising a 3D matrix

[0 0;0 1;1 0;1 1]
ans =
     0 0
     0 1
     1 0
     1 1
>> size(ans)
ans =
     4 2
Hellp all,
   From the above code we see that the matrix defined is a 4*2 matrix.Now if I want to extend this to a 4*2*50 matrix and initialise it with whatever values I want how can I do it in matlab?Pls tell me.thanx

x = zeros(4,2,50);

Write code of whatever form needed to initialize it. If you mean you
want all 50 planes identical

y = repmat(x, [1 1 50]);

is one way

Thank you for this information.It was really helpful.
