Syntax

tf = hasData(fr)

Description

tf = hasData(fr) checks if a radar data cube is available to read using the read function from the index of read pointer specified by CurrentPosition property of the dca1000FileReader object, fr. The function returns true if a data cube is available, and returns false if no more data cubes are available to be read.

Examples

Read all IQ data cubes one-by-one from the binary files recorded using the class dca1000

Create a dca1000FileReader object by specifying the file location where the recorded files are stored.

fr = dca1000FileReader(RecordLocation = "C:\Users\abc\dca1000data")
fr =
 
  dca1000FileReader with properties:
 
                 BoardName: "IWR6843ISK"
                ConfigFile: "C:\Users\abc\dca1000data\Range10Hz.cfg"
            RecordLocation: "C:\Users\abc\dca1000data"
          RecordFilePrefix: "iq_data"
   NumDataCubes: 63

Read all radar data cubes one-by-one in a loop until no more data cubes are available for reading. As long as data available, hasData returns true which keeps the loop running.

while hasData(fr)
        iqData = read(fr);
     end

Input Arguments

collapse all

dca1000FileReader object with the default or specified properties.

Output Arguments

collapse all

Status of availability of remaining radar data cubes available to read using the read function from the index of read pointer specified by CurrentPosition property of the dca1000FileReader object. The function returns true if a data cube is available, and returns false if no more data cubes are available to be read.
