<title>Description</title>
<para>writes row-by-row a real matrix or a column vector of character
strings in a formatted file. Each row of the <literal>a</literal> argument
begin in a new line of <literal>file-desc</literal> file. Depending on
<literal>format</literal> a given row of the <literal>a</literal> argument
may be written in more than one line of <literal>file-desc</literal>
file.
</para>
<para>
Format examples : <literal>(1x,e10.3,5x,3(f3.0))</literal> ,
<literal>(10x,a20)</literal> ;
</para>
<para>See a Fortran book for more precision.</para>
<para>Direct access files :
<literal>x=write(file_desc,a,k,format)</literal>. Here
<literal>k</literal> is the vector of records (one record by row, i.e.
<literal>m=prod(size(k)</literal>)
</para>
<para>
<literal>write(%io(2),....)</literal> writes on Scilab's window.
Note that in this case <literal>format</literal> should produce one output
line per matrix row. If this contraint is not verified unpredictable
behavior could happen.
