    20## @deftypefn {Function File} {} celldisp (@var{c}, @var{name})

    21## Recursively display the contents of a cell array.  By default the values

    22## are displayed with the name of the variable @var{c}.  However, this name

    23## can be replaced with the variable @var{name}.  For example:

    24## 

    25## @example

    26## @group

    27## c = @{1, 2, @{31, 32@}@};

    28## celldisp(c, "b")

    29##      @result{}

    30##         b@{1@} = 

    31##          1

    32##         b@{2@} = 

    33##          2

    34##         b@{3@}@{1@} = 

    35##          31

    36##         b@{3@}@{2@} = 

    37##          32

    38## @end group

    39## @end example
