Simple Markov chain simulation by external call to random() C function :
|
|
|
|
- random.epi : Heptagon interface containing the declaration of
|
|
random() function
|
|
|
|
- random.h, random.c : "glue" between actual random() C function and
|
|
function calls generated by Heptagon
|
|
|
|
- markov.ept : contains node "process", simulating a two-state Markov
|
|
chain, with probability p (constant) at each step to go from one
|
|
state to the other
|
|
|
|
Function "random" and node "process" are declared unsafe to avoid
|
|
optimization removing calls to "random" ("random" has side effects).
|
|
|
|
Compilation and simulation :
|
|
|
|
heptc random.epi
|
|
heptc -target c -s process -hepts markov.ept
|
|
gcc -I . -I markov_c -I /usr/local/lib/heptagon/c random.c markov_c/_main.c markov_c/markov.c markov_c/markov_types.c -o markov
|
|
hepts -mod Markov -node process -exec ./markov
