  * The output argument was documented only on en_US
  * The input was restricted to matrices, while any Scilab object is acceptable.
  * The setfield usefullness specific to mlists was not clearly described
  * The example had no call to setfield for fr_FR ja_JP pt_BR and ru_RU versions
    It did not illustrate the setfield role for mlists.
  * See also: + getfield
  * History was incompleted for en_US and missing for other languages
