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
• 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.
lcpack length of packed field cpack. Will be set to -1 if missing value management field is not 1 or
2.
