Hello everyone!(adsbygoogle = window.adsbygoogle || []).push({});

I just start using C programming as i execute a numerical method in MATlab for a heat diffusion problem. I have solve my problem but my code can be a little better. HERE is part of my code and i use comments to ask for help!

for i=2:10

E(i,1)=20;

T(i,1)=1;

Q(i,1)=0;

end

for t=1:50

for i=1:11

R(i,1)=E(i,1);

end

for m=1:100 %this is the loop i want to exit,it counts iterations%

Sum=0;

for i=2:10

T(i,1)=a*E(i,1)+b*(E(i-1,1)+E(i+1,1)+T(i-1,1)+T(i+1,1)); %9 temperatures i want

end %to calculate%

for i=2:10

Sum=Sum+abs(T(i,1)-Q(i,1)); %this is the error i want to calculate%

end

if Sum<=0.001 % when this is true i want to leave the "m" loop%

m=101; % here is the help that i need,i want to leave the "m" loop%

else %without changing the value of m,in fact i want to know how many%

for i=2:10 %iterations i need until the error is <=0%

Q(i,1)=T(i,1);

end

end

end

for i=2:10

E(i)=T(i);

end

end

i read something about "break" but i m not sure how to use it

Thanks a lot for your time!
