Good morning sir/madam,
Please find the attached text file name Ocb_pl.txt
I would like to extract data from 136th line to 141th line 1Displ 2Displ values in array format (n*1) format 1 Displ 2 Displ of node 1 and 1 Displ 2 Displ of node 2 and so on in generalised code if we dont know which line these values belongs to. Any help would be greatly appreciated. Thank you in advance.
The below is for your reference. Thank you

fid = fopen("Ocb_pl.txt") ;
S = textscan(fid,"%d %f %f %f %f\n",'HeaderLines',135) ;
fclose(fid) ;
S{1}

Thank you for your response Srinivas. This i tried it before. But it can only scan136th line but i need to scan till 141th line and that too we dont know in which line extracting data present but we know what data we need to extract
The below is the lines we need to extract data from text file. I think search scan might be helpfull but i dont know how to use it. Any help would be greatly appreciated. Thank you in advance
