Hi,
I have a hex file containing 8-bit hex values which are actually 16-bit signed values. For example in the screenshot below, the values should be x27F0, x22E0, x22E0, x1D40, x1D40, x1DB0 etc. I also uploaded the hex file. (Also, even though they are signed, most of the time sign bit will be 0, ignore it please.) Now, I want to plot these data but I do not know how can I read them in the first place. Can you please help me?

filename = 'output2.txt';
fid = fopen(filename, 'r', 'ieee-be');
data = fread(fid, '*int16');
fclose(fid);
data(1:2)
dec2hex(data(1:2))
