I am trying to import specific number of lines from an output text file. I have used the textscan command to import the required lines. The imported data consists of 1000x1 cells (see the figure below). Any idea how to convert these cells into three separate columns?
% open the file
fid=fopen('dbe-ew-transient analysis - 5% critical damped.f06');
% set linenum to the desired line number that you want to import
linenum = 165164;
% use '%s' if you want to read in the entire line or use '%f' if you want to read only the first numeric value
C = textscan(fid,'%s',1000,'delimiter','\n', 'headerlines',linenum-1);
M = C{:};
Thanks in advance.

"I struggled with the file format, i.e., "*.f06", which is not pupular"
The file extension is irrelevant, you just need tell them that it is a text file using the option: "FileType","text":

The comments in the code suggest how to do this. Using the attached test file with some header lines to skip:
fid = fopen('test.txt');
% set linenum to the desired line number that you want to import
linenum = 4;
% use '%s' if you want to read in the entire line or use '%f' if you want to read only the first numeric value
C = textscan(fid,'%f %f %f',1000,'delimiter','\n', 'headerlines',linenum-1);
fclose(fid);
C = cell2mat(C)
C = 5×3
1.0e+04 * 0.0001 1.0002 0.0000 0.0002 1.0002 0.0000 0.0003 1.0002 0.0000 0.0004 1.0002 0.0000 0.0005 1.0002 0.0000

fn ='dbe-ew-transient analysis - 5% critical damped.f06';
linenum = 165164;
M = readmatrix(fn, 'Range', 165164+":"+999);
