Read file txt and input value in Matlab

1 view (last 30 days)
Hi,
I want to read txt file and input value in Matlab. I use "dlmread" but it is always error:
"Error using dlmread (line 141) Mismatch between file and format string. Trouble reading number from file (row 1u, field 1u) ==> ITEM: TIMESTEP\n"
This is code:
...
clear
clc
filename = 'posi.txt';
M_initial = dlmread(filename,' ',1,0)
clear filename
...
The 'posi.txt' file was attached.
Anyone can tell what can be done in this case?

For some reason, testing for the end of file (with feof) doesn’t work with this file. A for loop and guessing at the number of ‘sections’ in the file will have to do:
fidi = fopen('posi.txt', 'rt');
for k1 = 1:20
data{k1} = textscan(fidi,'%f%f%f%f%f', 'HeaderLines',9, 'Delimiter',' ', 'CollectOutput',1);
fseek(fidi, 1, 0);
end
fclose(fidi);

Which MATLAB version are you using? Only quite recently has dlmread() been able to handle text anywhere in the file.

They are output. So I need read this txt in Matlab and analyze again.
