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);
