i have problem in bisection method.

i'm having a problem while using "inline" for bisection, here are my script

function c=bisection(f, a, b, maxit,tol)
if nargin < 5, tol=1e-4; end
if nargin < 4, maxit=100; end
if f(a)*f(b)>0
    c='failure';
    return
end
disp('    n     a      b      c     (b-a)/2')
for i=1:maxit
    c=(a+b)/2;
    if f(c)==0
        return
    end
    fprintf('%d \t %d \n', i,    a,     b,     c,    (b-a)/2)
    if (b-a)/2 < tol
        return
    end
    if f(b)*f(c)>0
        b=c;
    else a=c;
    end
end
c='failure';

and this is i got in command window

please help :))

Stop using inline. Use function handles or anonymous functions instead.

f = @sin;
g = @(x) cos(x+1);
