Matlab reads the data of dat file, but the file is too large. What should I do if I want to try a small part? This file is a one-dimensional array with 8 unsigned bits.
With fseek, you can locate the location pointer of the file.
fid=fopen(' 1.dat，' r ')
fseek(fid， 10000，- 1)
For i= 10000: 15000.
values(i)=fscanf(fid，' %d %d ')
end
fclose(fid)
The key is the location of fseek, such as 10000 here. As long as the location is found, the location can be saved in the matrix.
