Main IVP Solver Function

[t,y] = solve_ivp(f,[t0,tf],y0,h)
[t,y] = solve_ivp(f,{t0,E},y0,h)
[t,y] = solve_ivp(__,method)
[t,y] = solve_ivp(__,method,wb)

Matrix-Valued IVP Solver Function

[t,M] = solve_ivp_matrix(F,[t0,tf],M0,h)
[t,M] = solve_ivp_matrix(F,{t0,E},M0,h)
[t,M] = solve_ivp_matrix(__,p,method)
[t,M] = solve_ivp_matrix(__,p,method,wb)
