MATLAB: How to read different bits from a binary file

binary daradifferent bits

Hi. I am trying to read a binary file with MATLAB which contains different bits (8-bits and12-bits).

I read stream 1 easily with ('*uint8'). But can you help me to read stream 2 and 3 from the binary file, please?

Just employ: 'unit16' instead of 'uint8'.

MATLAB: Copy a line from a txt to other txt

Hi!

count = 1;
tline = fgetl(fid01);
while ischar(tline)
count = count + 1;
disp(tline)
if count == 3
fprintf(fid02,'%s\r\n',tline);
end
tline = fgetl(fid01);
end 
fclose(fid01);
fclose(fid02);

You can do as well

for n = 1:3
tline = fgetl(fid01);
end
fprintf(fid02,'%s\r\n',tline);
fclose(fid01);
fclose(fid02);

MATLAB: Fwrite sometimes uses 5 bytes to write a 4-byte single

If you want to use fwrite() you should not be opening the file as a text file ('wt'). Opening as a text file tells the file system to convert the line terminator.

>> typecast(single(1.28),'uint8')
ans =
 10  215  163   63

10 happens to correspond to newline, so that is going to be converted to the byte sequence 13 10 215 163 63 (CR LF then some bytes)

When you are working with binary, leave the 't' off of 'rt' and 'wt'.
