Is an array containing the rank (number of dimensions) for each

field. NTYPE is a cell array of strings that denote the number

type of each field. If the routine fails, NFLDS is -1 and the

other output arguments are [].

SWinqattrs

[NATTR,ATTRLIST] = HDFSW('inqattrs',SWATH_ID)

Retrieve information about attributes defined in swath. NATTR is

the number of attributes found. ATTRLIST is a string containing a

comma-separated list of attribute names. If the routine fails,

NATTR is -1 and ATTRLIST is [].

SWnentries

[NENTS,STRBUFSIZE] = HDFSW('nentries',SWATH_ID,ENTRYCODE)

Retrieve number of entries and descriptive string buffer size for a

specified entity. ENTRYCODE can be one of the following:

'HDFE_NENTDIM' (dimensions), 'HDFE_NENTMAP' (dimension mappings),

'HDFE_NENTIMAP' (indexed dimension mappings), 'HDFE_NENTGFLD'

(geolocation fields), or 'HDFE_NENTDFLD' (data fields). NENTS is

the number of entries found, and STRBUFSIZE is the descriptive

string size. If the routine fails, NENTS is -1 and STRBUFSIZE is

[].

SWdiminfo

DIMSIZE = HDFSW('diminfo',SWATH_ID,DIMNAME)

Retrieve size of specified dimension. DIMNAME is the dimension

name. DIMSIZE is the size of the dimension. If the routine fails,

DIMSIZE is -1.

SWmapinfo

[OFFSET,INCREMENT,STATUS] = HDFSW('mapinfo',...

SWATH_ID,GEODIM,DATADIM)

Retrieve offset and increment of specific monotonic geolocation

mapping. GEODIM is the geolocation dimension name. DATADIM is the

data dimension name. OFFSET and INCREMENT are the offset and

increment of the geolocation dimension with respect to the data

dimension. STATUS is -1 and other outputs are [] if the operation

fails.

SWidxmapinfo

[IDXSZ,INDEX] = HDFSW('idxmapinfo',SWATH_ID,GEODIM,...

DATADIM)

Retrieve indexed array of specified geolocation mapping. GEODIM is

the geolocation dimension name. DATADIM is the data dimension

name. IDXSZ is the size of the indexed array. INDEX is the index

array of the mapping. If the routine fails IDXSZ is -1 and INDEX

is [].

SWattrinfo

[NTYPE,COUNT,STATUS] = HDFSW('attrinfo',SWATH_ID,...

ATTRNAME)

Returns information about a swath attribute. ATTRNAME is a string

containing the name of the attribute. NTYPE is a string containing

the HDF number type of the attribute. COUNT is the number of bytes

in the ATTRIBUTE. STATUS is -1 and other outputs are [] if the

operation fails.

SWfieldinfo

[RANK,DIMS,NTYPE,DIMLIST,STATUS] = HDFSW('fieldinfo',...

SWATH_ID,FIELDNAME)

Returns information about a specific geolocation or data field in

the swath. FIELDNAME is a string containing the name of the field.

RANK is the rank (number of dimensions) of the field. DIMS is an

array containing the dimension sizes of the field. NTYPE is a

string containing the HDF number type of the field. DIMLIST is a

string containing a comma-separated list of the dimensions in a

field. STATUS is -1 and other outputs are [] if the operation

fails.

SWcompinfo

[COMPCODE,COMPPARM,STATUS] = HDFSW('compinfo',...

SWATH_ID,FIELDNAME)

Retrieves compression information about a field. FIELDNAME is a

string containing the field name. COMPCODE is the HDF compression

code, and can be 'rle', 'skphuff', 'deflate', or 'none'. COMPPARM
