%IMPORTFILE Import numeric data from a text file as column vectors.
%   [VARNAME1,VARNAME2,BIAS_DRIVE_BIAS_ON] = IMPORTFILE(FILENAME) Reads
%   data from text file FILENAME for the default selection.
%
%   [VARNAME1,VARNAME2,BIAS_DRIVE_BIAS_ON] = IMPORTFILE(FILENAME, STARTROW,
%   ENDROW) Reads data from rows STARTROW through ENDROW of text file
%   FILENAME.

% Example:
%   [VarName1,VarName2,bias_drive_bias_on] = importfile('charge_measETMX1187479491.txt',1, 5);

%% Close the text file.

%% Post processing for unimportable data.
% No unimportable data rules were applied during the import, so no post

% unimportable data, select unimportable cells in a file and regenerate the
% script.

%% Allocate imported array to column variable names
