function REFERENCE = importReferencefile(filename, startRow, endRow) %IMPORTFILE Import numeric data from a text file as a matrix. % REFERENCE = IMPORTFILE(FILENAME) Reads data from text file FILENAME for % the default selection. % % REFERENCE = IMPORTFILE(FILENAME, STARTROW, ENDROW) Reads data from rows % STARTROW through ENDROW of text file FILENAME. % % Example: % REFERENCE = importfile('REFERENCE.csv', 1, 409); % % See also TEXTSCAN. % Copyright (c) 2016, MathWorks, Inc. % Auto-generated by MATLAB on 2016/06/18 16:21:14 %% Initialize variables. delimiter = ','; if nargin<=2 startRow = 1; endRow = inf; end %% Format string for each line of text: % column1: text (%s) % column2: double (%f) % For more information, see the TEXTSCAN documentation. formatSpec = '%s%f%[^\n\r]'; %% 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.
