One method for finding a root of a function is the bisection method. Here is a nice writeup on the bisection method: http://www.mathwarehouse.com/calculus/continuity/continuity-bisection-method.php (Links to an external site.)Links to an external site.
Write a function bisect( ) that finds the root of a polynomial ax3+bx2+cx+d over an interval [A,B]. The function takes as input the coefficients a, b, c, d, and the interval limits A and B. The function returns as output the value of the root over the interval [A,B], if it exists. The function also returns as output a message (flag) that informs the user if no roots exist over the interval [A,B]. It should be clear that you cannot use any of MATLAB's built-in root finding functions to do this problem. Use the bisection method.
a = -1;
b = 1;
c = -1;
d = 10;
A = 0;
B = 5;
[root,flag] = bisect(a,b,c,d,A,B)
