Subject: parallel program in matlab for 4 loop
I want to solve 4 nonlinear equation using Matlab. 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 x(1),x(2),x(3),x(4));

f2=nonlinear equation2(include variable x(1),x(2),x(3),x(4));

f3=nonlinear equation3(include variable x(1),x(2),x(3),x(4));

f4=nonlinear equation4(include variable x(1),x(2),x(3),x(4));

mufunc is include f1,f2,f3,f4,

for x1 =1: 200

for x2=1:200

for x3 =1:200

for x4 1:200

x0=[x1,x2,x3,x4];

answer:=fsolve(@myfunc(x),x0};

end

end

end

end

But this program takes time. 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?
