FINDING ROOTS
The roots() Function
For values of polynomials equated to zero, finding the root using MATLAB is
quite easy. The available function is
roots(), which has a format roots(coef)
where coef is a vector containing the coefficients of the polynomial presented in
descending powers of x.
Let us apply the function with this example problem.
Example Problem 7.2. A cylinder tank is to be filled
