運行下面簡單的程序，二分法求方程的根，調(diào)試的時候在循環(huán)處設斷點，繼續(xù)系統(tǒng)就退出了，直接運行沒有問題

f=@(x)sin(x);

a=-1;

b=pi/2;

e=1e-8;

k=100;

a0=a;

b0=b;

x=(a0+b0)/2.0;

fa = f(a);

fb = f(b);

fx=f(x);

while(abs(fx) > eps)

if (sign(fx)*sign(fa) < 0)

b0 = x;

fb = fx;

else

a0 = x;

fa = fx;

end

x = (a0+b0)/2.0；

fx=f(x);
