Roots function - Polynomials:

The roots function in MATLAB is used to find the roots of an equation represented by a polynomial. For illustration, for the mathematical function (Note that this is a mathematical expression, not a MATLAB!),

f(x) = 4x3 - 2x2 - 8x + 3

to compute the equation f(x) = 0:

>> roots([4 -2 -8 3])

ans =

   -1.3660

    1.5000

    0.3660
