Hi I would like to read off a text file at location 414 from the beginning of file,it consists of 0.31158E+02 -0.15094E+03 -0.13590E-04 I would like to read the first character from the text file as how it is given but I can only obtain a rounded up value of 32 instead of 0.31158E+02 . How can I go about this?

fid=fopen('textfile.m');

>> fseek(fid,414,'bof');

>> X=fread(fid,1,'schar')

X = 32

"... I can only obtain a rounded up value of 32..."

Most probably that is a space character, which has nothing to do with your number at all.
