%IMPORTFILE Import numeric data from a text file as column vectors.
%   [VARNAME1,VARNAME2,VARIA] = IMPORTFILE(FILENAME) Reads data from text
%   file FILENAME for the default selection.
%
%   [VARNAME1,VARNAME2,VARIA] = IMPORTFILE(FILENAME, STARTROW, ENDROW)
%   Reads data from rows STARTROW through ENDROW of text file FILENAME.
%
% Example:
%   [VarName1,VarName2,VARIA] = importfile('kazr20180201-Zcor=1.80000.dat',3, 162173);

%% Post processing for unimportable data.

% script.
