+## @deftypefn{Function File} {@var{result} =} map (@var{function}, @var{iterable}, @dots{})
+## Apply @var{function} to every item of @var{iterable} and return the results.
+##
+## @code{map}, like Lisp's ( & numerous other language's ) function for
+## iterating the result of a function applied to each of the data
+## structure's elements in turn. The results are stored in the
+## corresponding input's place. For now, just will work with cells and
+## matrices, but support for structs are intended for future versions.
+## Also, only "prefix" functions ( like @code{min (a, b, c, ...)} ) are
+## supported. FUN_HANDLE can either be a function name string or a
+## function handle (recommended).
+##
+## Example:
+## @example
+##
+## octave> A
+## A
+## @{
+## [1,1] = 0.0096243
+## [2,1] = 0.82781
+## [1,2] = 0.052571
+## [2,2] = 0.84645
+## @}
+## octave> B
+## B =
+## @{
+## [1,1] = 0.75563
+## [2,1] = 0.84858
+## [1,2] = 0.16765
+## [2,2] = 0.85477
+## @}
+## octave> map(@@min,A,B)
+## ans =
+## @{
+## [1,1] = 0.0096243
+## [2,1] = 0.82781
+## [1,2] = 0.052571
+## [2,2] = 0.84645
