xtitle add titles on a graphics window

## Syntax

    xtitle(title,[x_label,[y_label,[z_label]]],<opts_args>)

## Arguments

title,x_label,y_label, z_label

  matrices of strings.

  Starting from Scilab 5.2, it is possible to write LaTeX or MathML expression.

<opt_args>

  a sequence of statements `key1=value1, key2=value2` ,... where keys may be `boxed` (see below). In this case, the order has no special meaning.

boxed

  an integer value. If it is 1, a box is drawn around each title.

## Description

`xtitle` add titles on a 2D or 3D plot. `title` is the general title and x_label, y_label and z_label are the titles on the three axis. If the arguments are matrices, each line of the matrices is displayed on a different line.

Enter the command `xtitle()` to see a demo.

## Examples

    plot3d() ;
    // puts the titles
    xtitle( 'My surface is blue', 'X axis', 'Y axis', 'Z axis' ) ;
    // draw a box around the titles
    xtitle( 'My surface is blue', 'X axis', 'Y axis', 'Z axis', boxed = %t );

    // With LaTeX & MathML:
    mathml="<mrow>      <mfrac>        <mrow>          <mi>d</mi>          <mi>y</mi>        </mrow>        <mrow>          <mi>d</mi>          <mi>x</mi>        </mrow>      </mfrac>      <mo>=</mo>      <mfrac>        <mn>1</mn>        <msup>          <mi>y</mi>          <mn>2</mn>        </msup>      </mfrac>    </mrow>";

    xtitle( 'My surface is blue', 'X axis', '$Y axis$', mathml );

plot3d() ; xtitle( 'My surface is blue', 'X axis', 'Y axis', 'Z axis' ) ;
