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
