Bisection Method, For Numerical analysis. working matlab code. numeric analysis Bisection method. MATLAB provides tools to solve math. Using linear programing techniques we can easily solve system of equations. This file provides a running code of Bisection Method

1. function [r] = ncasinmt(f,a,b,N,eps)
f = inline('x^3-9*x+1')
a=2;
b=4;
N=18;
eps=0.0001;
if(f(a)==0)
r=a;
return;
elseif(f(b)==0)
r=b;
return;
elseif(f(a)*f(b)>0)
error('f(a) and f(b) donot have opposite sign')
end
for i = 2:N
c=(a+b)/2;
if(f(c)==0)
r=c;
return;
elseif(f(a)*f(c)<0)
b=c;
else a=c;
end
if (b-a)/2<eps;
if(abs(f(a))<abs(f(b))&&abs(f(a))<eps)
r=a;
return;
elseif(abs(f(b))<eps)
r=b;
return;
end
end
end
