function Ch2 = importfile(filename, dataLines)
%IMPORTFILE Import data from a text file
%  CH2 = IMPORTFILE(FILENAME) reads data from text file FILENAME for the
%  default selection.  Returns the data as a table.
%
%  CH2 = IMPORTFILE(FILE, DATALINES) reads data for the specified row
%  interval(s) of text file FILENAME. Specify DATALINES as a positive
%  scalar integer or a N-by-2 array of positive scalar integers for
%  dis-contiguous row intervals.
%
%  Example:
%  Ch2 = importfile("C:\Users\HP\Videos\UIDT\M6\Señales\Directo\1_Ch2.csv", [1, Inf]);
