<title>Description</title>
<para>converts a matrix into a matrix of strings.</para>
<para>If <literal>x</literal> is a function
<literal>[out, in, text]=string(x)</literal> returns three vectors strings :
<literal>out</literal> is the vector of output variables,
<literal>in</literal> is the vector of input variables, and
<literal>text</literal> is the (column) vector of the source code of the
function.</para>
<para>If <literal>x</literal> is a <literal>lib</literal> variable (library), text
is a character string column vector. The first element contains the path
of library file and the other the name of functions it defines.</para>
<para>Character strings are defined as <literal>'string'</literal>
(between quotes) or <literal>"string"</literal> (between doublequotes);
matrices of strings are defined as usual constant matrices.</para>
<para>Concatenation of strings is made by the <literal>+</literal>
operation.</para>
<para>For complex, real, integer, polynomial matrix <literal>string</literal> output is managed by <link linkend="format">format</link> function (see examples).</para>
