.. us.tag  fspline2 NOTREADYENGLISH interpol-2d New5200

:ref:`fspline2` executes a 2-dimensional "matrix to matrix" interpolation.

.. function::  rmZi = fspline2(rvX, rvY, rmZ, rvXi, rvYi, rsSmoothFactor)

.. us.return

**Return Value**

*rmZi* is the interpolated matrix for the given *rvXi* and *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
   
   *rvX* is a vector with x-coordinates for the new matrix *rmZi*.

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

.. uparam:: rsSmoothFactor
   
   *rsSmoothFactor* is a number equal or greater than 0.0. No smoothing is
   performed for 0.0.
