Hello, I'm new to matlab and I've got a question about outputting matrix to a pgm file. I know the most direct way of doing this is using imwrite function, but I want to ask if there's any other method or code that could output the matrix to pgm file without using imwrite function, for example, using functions like fwrite? Please let me know if there's any idea.

Yes, the PGM file format is relatively simple. You can fopen(), fprintf() several times, and fclose()
It is not clear why you would want to do this yourself, but...
Note: if you are writing uint16 data, then the most significant byte must be first -- corresponding to fopen() with 'ieee-be' option.
