<title>Description</title>
<para>This help describes how boolean and matrix of booleans can be handle
through the <link linkend="call_scilab">Call Scilab API</link> and <link linkend="api_scilab">api Scilab</link>.
</para>
<para>There are several functions which can be used to read / write from
the memory of Scilab. These functions are described in dedicated
pages.

<note>
Note: Access to variables is done through <link linkend="api_scilab">api Scilab</link> (named variable).
