%IMPORTFILE Import numeric data from a text file as column vectors.
%   [DATE1,TIME,CALLSIGN,LAT,LONG,ALT,INVALID] = IMPORTFILE(FILENAME) Reads
%   data from text file FILENAME for the default selection.
%
%   [DATE1,TIME,CALLSIGN,LAT,LONG,ALT,INVALID] = IMPORTFILE(FILENAME,
%   STARTROW, ENDROW) Reads data from rows STARTROW through ENDROW of text
%   file FILENAME.
%
% Example:
%   [Date1,Time,Callsign,Lat,Long,Alt,Invalid] =
%   importfile('packets_processed.csv',2, 467);

%% Format string for each line of text:
%   column1: text (%s)
%	column2: text (%s)
%   column3: text (%s)
%	column4: double (%f)
%   column5: double (%f)
%	column6: double (%f)
%   column7: double (%f)
% For more information, see the TEXTSCAN documentation.

%% Open the text file.
fileID = fopen(filename,'r');

%% Read columns of data according to format string.
% This call is based on the structure of the file used to generate this
% code. If an error occurs for a different file, try regenerating the code
% from the Import Tool.

    end
end

%% Close the text file.

%% Post processing for unimportable data.
% No unimportable data rules were applied during the import, so no post
% processing code is included. To generate code which works for
% unimportable data, select unimportable cells in a file and regenerate the
% script.

%% Allocate imported array to column variable names

Callsign = dataArray{:, 3};
Lat = dataArray{:, 4};
