+% EXPORT export the data of an analysis object to a text file.
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% DESCRIPTION: EXPORT export the data of an analysis object to a text file.
+%              The x-values will be stored in the first column of the text
+%              file and the y-values the second column. If the y-values are
+%              complex then stores this method the real part of the
+%              y-values in the second column and the imaginary part in the
+%              third column.
+%
+% CALL:        export(a, 'blah.txt');
+%              export(a, plist);
