M2SCI function

mtlb_close - Matlab close emulation function

### Description

Scilab equivalent for Matlab `close` is different according to the current figure type (uicontrol or graphic one).

  - When current figure is a uicontrol one: Scilab equivalent for Matlab `close` is `close`
  - When current figure is a graphic one: Scilab equivalent for Matlab `close` is `xdel` or `delete`
  - In Scilab we do not get an error status.

The function `mtlb_close([h])` is used by `mfile2sci` to replace `close([h])` when it was not possible to know what were the inputs while porting Matlab code to Scilab. This function will determine the correct semantic at run time. If you want to have a more efficient code it is possible to replace `mtlb_close` calls:

  - If `h` is a uicontrol figure `mtlb_close(h)` may be replaced by `close(h)`
  - If `h` is a graphic figure `mtlb_close(h)` may be replaced by `delete(h)`

Caution: `mtlb_close` has not to be used for hand coded functions.
