MATLAB: Binary file read 16bit word in 2’s complement

binaryfreadtwo's complement

Hi everyone, I have a binary file and I'm trying to read 16bit words (values) in 2's complement (till the end of the file). Is this something that can be done with default Matlab functions 'fread'?! Or must I use some other technique (custom functions).

What happens if you simply try it with fread? Post the code and explain the remaining problems specifically.

MATLAB: 2’s complement of a row in a matrix

To construct the twos-complement of a binary vector, do a bit-wise negation of the vector, and then undertake the steps necessary to add 1 to the end of the vector, propagating any carry "left-ward" until there is no carry remaining.

MATLAB: How can i convert a file into a matrix

Hi,

you can always apply fileread to any file (and write it back with fopen,fwrite,flcose) but the main question will be: What do you want to do with the data you read into MATLAB?

tmp = fileread(FILENAME)
fid = fopen(OUTPUT_FILENAME,'w')
fwrite(fid,tmp,'*char')
fclose(fid)
