Hi friends, i have used this code with textscan:

fidpw= fopen('yy.txt','rt');
format = repmat('%s ',[1 row1]);
Pat = textscan(fidpw,format );
fclose(fidpw);

i used texscan to display the columns in this file but it doesn't work well because of the space existed in between the first rows of its corresponding columns

the columns looks like :

col1={stage iiib;t3;n1;m0}
col2={stage iv;t4;n1;m1}

code output looks like:

col1={stage;stage;t3;n1;m0}
col2={iiib;iv;t4;n1;m1}

?????

is this because i used %s in textscan ???

Thanks in advance!

In that situation, you should

Pat = textscan(fidpw, format, 'whitespace', '', 'delimiter', ';');

fid = fopen('Classeur1.txt', 'rt');
Pat = textscan(fid, fmt, 'Delimiter', '\t');
fclose(fid)

在 MATLAB Online 中打开

fid = fopen('my text file','r');
S = textscan(fid,'%s','delimiter','\n') ;
fclose(fid) ;
S = S{1} ;

Note that S will be a cell. You can access your required line using S{i} . Where i is your line number.
