+## @deftypefn {Function} {[@var{string}] =} asci ([@var{columns}])
+## Print ASCI table.
+##
+## If this function is called without any input argument and without any output
+## argument then print a nice ASCI-table (excluding special characters with
+## hexcode 0x00 to 0x20) on screen with four columns per default. If this
+## function is called with one output argument then return an ASCI-table string
+## and don't print anything on screen. Finally, if this function is called with
+## one input argument of type scalar then either print (no output argument) or
+## return (one output argument) an ASCI-table with a number of columns given in
+## @var{columns}.
+##
+## For example,
+## @example
+## A = asci (3);
+## disp (A);
+## @end example
+## @end deftypefn
