My program is not stop. I can not stop while command. Please help me.

clear all

clc

RV=0.31869940426982923;

AE=0;

error=10^-2;

k=1;

l=abs(AE-RV)

while l>error

k=k+1;

for i=1:k

a=[2.5-0.2]/k;

x_1=0.2+a*(i-1);

x_2=0.5+a*i;

y_1=sin(2*x_1);

y_2=sin(2*x_2);

if (y_1*y_2)<0

b=abs(x_2-x_1)/2*[abs(y_1)*y_1/(y_1+y_2)+abs(y_2)*y_2/(y_1+y_2)];

else

b=abs(x_2*x_1)*(y_1+y_2)/2;

end

AE=AE+b;

end

end

k

Couldn't see too well as your code is a bit of a wall of text, but does l ever get updated in your loop? If not then if the expression was true at the start, then it will always be true and the loop won't end
