Function Documentation
void cmplxpack (float * fld, g2int ndpts, g2int idrsnum, g2int * idrstmpl,unsigned char * cpack, g2int * lcpack)
Pack up a data field using a complex packing algorithm. This function 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. Must equal
2 or 3.
idrstmpl
Contains the array of values for Data
Representation Template 5.2 or 5.3
