Hi experts!(adsbygoogle = window.adsbygoogle || []).push({});

Here is my program.

%Bisection Method

clc

close all

clear all

f=input('Enter any Equation: ','s');

f=inline(f);

n=1;

a=input('Enter 1st guess: ');

b=input('Enter 2nd guess: ');

tol=input('Enter tolerance: ');

m=(a+b)/2;

while(abs(f(m))>tol)

n=n+1

if(f(m)*f(a)<0)

b=m

else

a=m

end

m=(a+b)/2;

end

fprintf('The root of equation is: %f\nNumber of iterations is: %d',m,n)

%END

I want to know how much time this program will take to calculate root of the given equation.

I tried it to do, i.e. given below,(The program below is with changes made for elapsed time)

%Bisection Method

clc

close all

clear all

f=input('Enter any Equation: ','s');

f=inline(f);

n=1;

tic

a=input('Enter 1st guess: ');

b=input('Enter 2nd guess: ');

tol=input('Enter tolerance: ');

m=(a+b)/2;

while(abs(f(m))>tol)

n=n+1

if(f(m)*f(a)<0)

b=m

else

a=m

end

m=(a+b)/2;

end

fprintf('The root of equation is: %f\nNumber of iterations is: %d',m,n)

sec=toc

fprintf('%f',sec)

%END

Is this modified version(using tic toc) correct?

Does this calculate the correct time? I don't think so.
