create symbolic expressions when using ndgrid

I try to use function Ndgrid to get the grid coordinators.

Such as

[X1,X2,X3,...,Xn] = ndgrid(x1gv,x2gv,x3gv,...,xngv)

Suppose that the grid vectors are as each columns in a matrix M of size m-by-n.

Can someone help me to get the expression in the brackets, i.e. x1gv,x2gv,x3gv,...,xngv, please?

Thank you.

[m, n] = size(M);
temp = mat2cell(M, m, ones(1, n) );
[X{1:n}] = ndgrid(temp{:});

temp2 = cellfun(@(v) v(:), X, 'uniform', 0);
result = horzcat(temp2{:});

Thank you so much, I thought the question has gone with wind.

If I understand correctly, you are trying to do something like this?

>> A = sym('A%d',[1 4]);
B = sym('B%d',[1 4]);
>> [D1,D2] = ndgrid(A,B)
D1 =
[ A1, A1, A1, A1]
[ A2, A2, A2, A2]
[ A3, A3, A3, A3]
[ A4, A4, A4, A4]
D2 =
[ B1, B2, B3, B4]
[ B1, B2, B3, B4]
[ B1, B2, B3, B4]
[ B1, B2, B3, B4]

Not really, thanks anyway. I learned a trick from the answer.
