matlab find roots of symbolic polynomial
To find the roots of a symbolic polynomial in MATLAB, you can use the solve
function. Here's an example of how to use it:
syms x
eqn = x^2 - 4*x + 3 == 0;
sol = solve(eqn, x);
In this example, we define a symbolic variable x
using the syms
function. Then, we define the polynomial equation eqn
using the symbolic variable x
. Finally, we use the solve
function to find the roots of the equation and store them in the variable sol
.
You can replace the equation x^2 - 4*x + 3 == 0
with your own polynomial equation. The solve
function will return the roots of the equation as a symbolic expression or a numeric value, depending on the input.
Please note that the solve
function may not be able to find symbolic solutions for all polynomial equations. In such cases, it may return numeric approximations instead.
