hello folks i am writing a C program to solve a partial differential equation and would like to use MMA to animate my results. it's an initial-value/time evolution problem, and i would like to graph the system as it evolves in time. the program uses the crank-nicholson algorithm. my first thought was to save the solution at every 50 or so time steps in a bunch of files and then graph the collection of files as a poor man's animation after my program has finished. here is my question: it would be *infinitely* more desirable to pass an array of values to mathematica while the C program is running, so i can get graphs the moment the program spits the data out. is there a way to call MMA from a C program and have it graph an array of values passed to it in the form of an array? i know this is asking for alot, so i won't be too disappointed if it can't be done, but if it can, i would be incredibly overjoyed. thanks. peter -- You can sum some of the series some of the time, But you can't sum all of the series all of the time. -=><=-+-+-=><=-+-+-=><=-+-+-=><=-+-+-=><=-+-+-=><=-+-+-=><=-+-+-=><=-+-+-=><=- I BOYCOTT ANY COMPANY THAT USES MASS ADVERTISING ON THE INTERNET
