:ref:`meshdom` creates two matrices to create
a dataset of the form z = f(x,y).

.. function::  <xx, yy> = meshdom(x, y)

.. us.return

**Return Value**

*xx* and *yy* are matrizes.

.. us.params

**Parameters**

.. uparam:: x

   is a vector with one or more elements.

.. uparam:: y

   is a vector with one or more elemenst.

**Example**

::

   nRC = 40
   xmin = 0.05-PI/2;
   xmax = 0.05+PI;
   ymin = -PI/2;
   ymax =  PI/2

   x = linspace(xmin, xmax, nRC);
   y = linspace(ymin, ymax, nRC);
   <xx, yy> = meshdom(x,y);
   zz = real(tan(xx + 1i * yy));
   hDoc = DocCreate();
   hPage = PageCreate();
   DocAddPage(hDoc, hPage);
   hLayer = LayerCreate();
   PageAddLayer(hPage, hLayer);
   hdata = XYZCreateFromMatrix("real(tan(xx + 1i * y))", ..
                   zz, [xmin, ymin, xmax, ymax]);
   LayerAddDataset(hLayer, hdata);
   LayerAutoScale(hLayer);
   PageReplot(hPage);

**Example 2**

::

   * <xx, yy> = meshdom([1,2,3], [4,5,6])
   * xx
