How to read with stdin in matlab

Question

I have a long Matlab script to process data. I want to send him a flag over stdin to say that I have new data to process. I also want to read the flag from stdout when it is processed.

In other words, I have a process A that sends a flag about once per minute to Matlab. I want Matlab to wait until it receives this flag.

Writing to stdout in the matlab process is as simple as calling fprintf. But how can I read from stdin? The documentation fopendoes not mention the input channel as well fread. How to get matlab script to read from stdin?
