How do you insert a row or a column into a cell array?

Dear Matlab community

I want to insert a row or a column into a cell array. How could I conduct that?

Best regards

No differently than with any other array -- although inserting in the middle somewhere requires copying (although with cell arrays, the actual data won't be copied)

c={rand(2),rand(2)}             % create starting cell array

c = 1×2 cell array
    {2×2 double}    {2×2 double}

c=[c(1) {rand(4,2)} c(2)]       % insert a new cell in the middle

c = 1×3 cell array
    {2×2 double}    {4×2 double}    {2×2 double}

NB: The cell array c itself must remain rectangular; as demonstrated the content in a cell can be anything. This with the orginal row vector can only insert a single row; with a 2D array will have to insert content for all rows/columns, etc., ...
