Making a 3D plot in a vectorized function

I have a vectorized function which accepts an input vector such as:
y=myfun(x)
where
x=[x(1) x(2)]
and I want to assign vectors in x(1) and x(2) in order to make 3D plot. Do you know how can I implement this?

Here's one way, using a cell array to hold the two vectors:
>> c = cell(1,2);
>> x = 1:10;
>> y = 1:20;
>> c{1} = x;
>> c{2} = y;
>> myfun(c)
where the file myfun.m has
function myfun(x)
[xx,yy] = meshgrid(x{1},x{2});
zz = xx + yy.^2;
figure
mesh(xx,yy,zz)
end

Unfortunately, I do not have the symbolic toolbox. I suggest that you take this latest comment you just made, and create a brand-new question out of it. It seems much clearer now what you are trying to do. Probably you will find some help.
