Use the fzero function to find the roots of a polynomial in a specific interval. Among other uses, this method is suitable if you plot the polynomial and want to know the value of a particular root. For example, create a function handle to represent the polynomial 3x7+4x6+2x5+4x4+x3...
Roots of a polynomial are the values for which the polynomial equates to zero. So, if we have a polynomial in ‘x’, then the roots of this polynomial are the values that can be substituted in place of ‘x’ to make the polynomial equal to zero. Roots are also referred to as Zeros...

This MATLAB function, where r is a vector, returns the coefficients of the polynomial whose roots are the elements of r.
I want to find the roots of the following fractional order polynomial: P=s^2.1+2*s^1.2+1; Using the solve() function (solve(s^2.1+2*s^1.2+1)), Matlab finds some roots but how does Matlab compute them? Whats the algorithm?
Multidimensional Polynomial Root Finding4th order polynomials have explicit solutions, so you can construct the solutions symbolically and then use matlabFunction() to convert that to a function handle. Then apply that function handle to grids of the list of values over time, [A, B, C, D, E]...
