i read the datapoints by using importdata... but this is not suited for large number of data points....i have to design a notch filter with this data....so i have to read 14000 data points from a file.... what i have to do??

How many columns per line? What separator between columns? Are there any headers? What would a typical line look like?

fid = fopen('YourFile.txt');
datacell = textscan(fid, '%f%f', 14000, 'CollectOutput', 1);
fclose(fid);
youdata = datacell{1};

This is the reason I asked about the file format.
fid = fopen('YourFile.txt'); datacell = textscan(fid, '%*f%f%f%*f%*f%*f%*f', 14000); fclose(fid); A = datacell{1}; B = datacell{2}; C=A-B;
