File write in MATLAB

Hi, I used fread (fileptr, 2048, 'bit14', 2) to read 2048 samples of 14 bit data from a file. When I tried writing the same values to an output file using fwrite (fileptr, 2048, 'bit14', 2). I see that the bytes are swapped. Can anyone help on this issue?

You define the byte ordering in the FOPEN command. See te machineformat argument.

Hi, thank you for the tip. I used the options but not sure what to use. I am using a windows PC with XP os. For windows, the machine format is 'l' (little endian). So I used the 'l' option, but it did not help.

@Harish: Little-Endian is the default on PCs. But I assume, your original files are written in Big-Endian format. Therefore I suggest to specify Big-Endian for reading and writing the binary file.
