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:
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
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.
