Create a mesh with four variables

Hello,
I've got my x, y and z components which contain four variables. I would like to know if there is a matlab function, similar to meshgrid, which creates a 4^n x 4^n matrix.
Thank you
Ben

Maybe, but the output size would seem to be entirely wrong. ndgrid() would be used to create an (n x n x n x n) = n^4 array, not a 4^n x 4^n array.
[C1, C2, C3, C4] = ndgrid(component1_values, component2_values, component3_values, component4_values);
x = f1(C1, C2, C3, C4);
y = f2(C1, C2, C3, C4);
z = f3(C1, C2, C3, C4);
For example,
x = C1.^3 - 5*C2.^2 + cos(C3) - arctan(C4);

Hi Kawak,
You are not reading the result correctly. For example, X1 here is a 4-dimensional array. So to look for a given point, you need to find the corresponding element in each of these four matrices. For example
>> [X1(1,1,1,1) X2(1,1,1,1) X3(1,1,1,1) X4(1,1,1,1)]
ans =
0 0 0 0
