How to split a cell array into individual rows

I have a cell array of the following format:

C =

  2×2 cell array

    {3×2 double}    {3×18 sym}
    {5×2 double}    {5×18 sym}

I would like to split that cell array such that the row of within each cell becomes an individual cellarray row:

    C =

  8×2 cell array

    {1×2 double}    {1×18 sym}
    {1×2 double}    {1×18 sym}
    {1×2 double}    {1×18 sym}
    ...             ...
        

However I am not able to find a way to perform the above. Any help would be appreciated.

C = {randi(9,3,2), sym(randi(9,3,18)); randi(9,5,2), sym(randi(9,5,18))}

C = 2×2 cell array
    {3×2 double}    {3×18 sym}
    {5×2 double}    {5×18 sym}

temp = cellfun(@(c) num2cell(c,2), C, 'uniform', 0);
temp2 = arrayfun(@(IDX) vertcat(temp{:,IDX}), 1:size(temp,2), 'uniform', 0);
newC = horzcat(temp2{:})

newC = 8×2 cell array
    {[5 7]}    {1×18 sym}
    {[2 7]}    {1×18 sym}
    {[9 5]}    {1×18 sym}
    {[2 3]}    {1×18 sym}
    {[2 7]}    {1×18 sym}
    {[3 1]}    {1×18 sym}
    {[5 9]}    {1×18 sym}
    {[4 2]}    {1×18 sym}
