    plot array outside of C-program


    C newbie here. I'd like to be able to plot a simple line graph of an array created in my C-program. I can easily plot an array with Octave but how do I get an array from my C-program to Octave?

    Thanks for any help,

    myprog | octave

    Basically, you find out what sort of inputs your plot program can cope with (say from stdin) and you make your C program conform to that interface.

    If it's particularly crusty, you may need a file
    myprog -out=temp.txt
    octave -in=temp.txt

    Essentially, a series of printf statements to output the array as text is one way.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Thanks for the reply.
    I think i kind of did like you said. I sent my output to a text file, then that file into octave.

    Thanks again,
