:ref:`spline2` executes a 2-dimensional "matrix to matrix" interpolation.

.. function::  rmZi = spline2(rvX, rvY, rmZ, rvXi, rvYi)

.. us.return

**Return Value**

*rmZi* is the interpolated matrix for the *rvXi*, *rvYi* coordinates.

.. us.params

**Parameters**

.. uparam:: rvX
   
   *rvX* is a vector with x-coordinates for the matrix *rmZ*.

.. uparam:: rvY
   
   *rvY* is a vector with y-coordinates for the matrix *rmZ*.

.. uparam:: rmZ
   
   *rmZ* is a matrix.

.. uparam:: rvXi
   
   *rvXi* is a vector with x-coordinates for the new matrix *rmZi*.

.. uparam:: rvYi
   
   *rvYi* is a vector with y-coordinates for the new matrix *rmZi*.
