 Función:   [varargout] = op_aux_equalize_dimensions(expand_empty,varargin)

 Propósito: Ajusta las dimensiones de los datos numéricos de entrada

 Entrada:   - expand_empty: Identificador para expandir o no las matrices
              vacías. Dos posibilidades:
              - 0: Las matrices de entrada vacías son devueltas de igual modo
              - Distinto de 0: Las matrices de entrada vacía se redimensionan
                en la salida y se rellenan de ceros
            - Resto de argumentos de entrada

 Salida:    - Tantos argumentos como argumentos de entrada se hayan pasado
              (sin contar 'expand_empty')

 Nota: Los datos de entrada no numéricos se devuelven como hayan sido pasados

 -- Function file: [X,Y] = op_fwd(LON,LAT,PARAMS)

     This function projects geodetic coordinates into cartesian
     projected coordinates in the defined cartographic projection using
     the PROJ function proj_trans_generic().

     INPUT ARGUMENTS:

        • LON contains by default the geodetic longitude.
        • LAT contains by default the geodetic latitude.
        • PARAMS is a text string containing the projection parameters
          in PROJ format (ONLY format ’+’ style is allowed, in any other
          case results are not guaranteed).

     OUTPUT ARGUMENTS:

        • X contains by default the X projected coordinates.
        • Y contains by default the Y projected coordinates.

     LON or LAT can be scalars, vectors or 2D matrices.  X and X will be
     according to the higher dimension input argument.  Angular units
     are by default radians and linear meters, although other can be
     specified in PARAMS, so LON and LAT must be congruent with PARAMS.
     The same applies to the coordinate order at input and output.

     If a projection error occurs the resultant coordinates for the
     affected points have both Inf value and a warning message is
     emitted (one for each erroneous point).

 -- Function file: [LON,LAT] = op_inv(X,Y,PARAMS)

     This function unprojects cartesian projected coordinates (in a
     defined cartographic projection) into geodetic coordinates using
     the PROJ function proj_trans_generic().

     INPUT ARGUMENTS:

        • X contains by default the X projected coordinates.
        • Y contains by default the Y projected coordinates.
        • PARAMS is a text string containing the projection parameters
          in PROJ format (ONLY format ’+’ style is allowed, in any other
          case results are not guaranteed).

     OUTPUT ARGUMENTS:

        • X contains by default the X projected coordinates.
        • Y contains by default the Y projected coordinates.

     X or Y can be scalars, vectors or 2D matrices.  LON and LAT will be

     are by default radians and linear meters, although other can be
     specified in PARAMS, so X and Y must be congruent with PARAMS.  The
     same applies to the coordinate order at input and output.

     If a projection error occurs the resultant coordinates for the
     affected points have both Inf value and a warning message is
     emitted (one for each erroneous point).

     This function transforms X/Y/Z/t, lon/lat/h/t points between two
     coordinate systems 1 and 2 using the PROJ function
     proj_trans_generic().

          coordinates (X or geodetic longitude) in the source system.

          coordinates (time) in the source system.
        • PAR1 is a text string containing the parameters for the source
          system, in PROJ ’+’ format, as EPSG code or as a WKT
          definition.
        • PAR2 is a text string containing the parameters for the
          destination system, in PROJ ’+’ format, as EPSG code or as WKT

          coordinates (X or geodetic longitude) in the destination
          system

     order at input and output.

     If a transformation error occurs the resultant coordinates for the
     affected points have all Inf value and a warning message is emitted
     (one for each erroneous point).
