Hi, I have 300*2 txt.file (as X and Y in two columns), I have to separate the first column from the second column and then plot the points. I use dlmread for this but it's doesn't work.

T = readtable('myfile.txt') ; % also read about load, importdata, textscan
x = T.(1) ;
y = T.(2) ;
plot(x,y)

Hi Amir, try these codes below but make sure you put the 'sample.txt' file that I attached into the same directory. Good luck.
reading = fopen('sample.txt');
formatspec=['%f',repmat('%*f',1,5)]; % 5 represents total columns - 1 the first column
data = textscan(reading,formatspec);
reading = fclose(reading);
data{:} % taking the first column
