Hi MATLAB experts,
I have following example:
Solve the equation 3x^2-2x-4
Create a vector to represent the polynomial, then find the roots.
>> p=[3 -2 -4];
I find the roots and wanted to return back the same polynomial coefficients i used the follwing code:
1.0000 -0.6667 -1.3333
But the coefficients are not the same as the original polynomial coefficients.
The question is how to get or return the original polynomial coefficients?
Thanks & regards,
