           *cpack, g2int *lcpack)

Function Documentation

   void cmplxpack (g2float * fld, g2int ndpts, g2int idrsnum, g2int * idrstmpl, unsigned char *
       cpack, g2int * lcpack)
       This subroutine packs up a data field using a complex packing algorithm as defined in the
       GRIB2 documention. It supports GRIB2 complex packing templates with or without spatial
       differences (i.e. DRTs 5.2 and 5.3). It also fills in GRIB2 Data Representation Template
       5.2 or 5.3 with the appropriate values.

       Parameters
           fld Contains the data values to pack.
           ndpts The number of data values in array fld
           idrsnum Data Representation Template number 5.N. Must equal 2 or 3.
           idrstmpl Contains the array of values for Data Representation Template 5.2 or 5.3

           • 0 Reference value - ignored on input, set by compack routine.

           • 1 Binary Scale Factor

           • 2 Decimal Scale Factor

           • 6 Missing value management

           • 7 Primary missing value

           • 8 Secondary missing value

           • 16 Order of Spatial Differencing ( 1 or 2 )

           cpack The packed data field (character*1 array)
           lcpack length of packed field cpack.
