I want to solve 4 nonlinear equation using maple. I want to find many roots of this 4 nonlinear equation.
I have no idea about initial condition so I use 4 for initial condition. my program is as follow:
f1:=nonlinear equation1(include variable q1,q2,p1,p2);
f2:=nonlinear equation2(include variable q1,q2,p1,p2);
f3:=nonlinear equation3(include variable q1,q2,p1,p2);
f4:=nonlinear equation4(include variable q1,q2,p1,p2);
for q11 from 1 to 200 do
for q22 from 1 to 200 do
for p11 from 1 to 200 do
for p22 from 1 to 200 do
answer:=fsolve({f1,f2,f3,f4},{p1=p11,p2=p22,q1=q11,q2=q22};
end do; end do; endo do; end do;
But this program takes time. It has 2 reason.
1-When fsolve cannot find a rood for a special initial condition fsolve take time to assign a variable (answer).
2- Because I use 4 for that it run 200*200*200*200 time.
Would you please tell me how can I decrease time process of my program?
How can I write this program in parallel program in maple?
Regards
