<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, 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>
