Revision as of 15:36, 11 August 2009

The differential equations for the Lotka Volterra fishing problem in C code read as follows

/* steady state with u == 0 */
double ref0 = 1, ref1 = 1;

/* Biomass of prey */
rhs[0] =   xd[0] - xd[0]*xd[1] - p[0]*u[0]*xd[0];
/* Biomass of predator */
rhs[1] = - xd[1] + xd[0]*xd[1] - p[1]*u[0]*xd[1];
/* Deviation from reference trajectory */
rhs[2] = (xd[0]-ref0)*(xd[0]-ref0) + (xd[1]-ref1)*(xd[1]-ref1);
