sde, a C code which illustrates properties of stochastic ordinary differential equations (SODE's), and common algorithms for their analysis, including the Euler method, the Euler-Maruyama method, and the Milstein method, making graphics files for processing and display by gnuplot, by Desmond Higham;

Source Code:

• sde_test.c, a sample calling program.
• sde_test.sh, runs all the tests.
