covert into 3D array

hey i have a 2D array having many elements like this:

    y=[4,1,1; 4,1,1; 4,1,1; 3,1,1; 4,1,-1; 3,1,-1; 4,1,1]

& a cell array:

    x{1,1}={4;4}
    x{2,1}{4;[3;4];[3;4]}

i want to compare elements of x with 1st column of y and convert that array into a 3D array accordingly.

thanks in advance.

    result(:,:,1)=[4,1,1]
    result(:,:,2)=[4,1,1]
    result(:,:,3)=[4,1,1]
    result(:,:,4)=[3,1,1;4,1,-1]
    result(:,:,5)=[3,1,-1;4,1,1]
