That is not possible. You will either have to use a cell array, or remove the values entirely.

{'',2,3,4,''}

ans = 1×5 cell array
    {0×0 char}    {[2]}    {[3]}    {[4]}    {0×0 char}

[2,3,4]

ans = 1×3

2 3 4

To add on to this answer, here is how you might convert xxx to a cell array and replace the NaNs with '':

xxx = [NaN 2 3 4 NaN];

nan_idx = isnan(xxx);
xxx = num2cell(xxx);
xxx(nan_idx) = {''};

display(xxx);

xxx = 1×5 cell array
    {0×0 char}    {[2]}    {[3]}    {[4]}    {0×0 char}
