The output of the given code snippet depends on the symbolic toolbox used by MATLAB. Here is the explanation of each function call:
- `disp(sol)` prints the value of the variable `sol` to the command window. The variable `sol` is not defined in the given code snippet, so this function call will result in an error.
- `root(z^3 - 3*z - 1, z, 1)` computes the first root of the polynomial `z^3 - 3*z - 1`. The output of this function call depends on the symbolic toolbox used by MATLAB. If the toolbox is installed and loaded, the output will be a symbolic expression representing the first root of the polynomial. Otherwise, this function call will result in an error.
- `root(z^3 - 3*z - 1, z, 2)` computes the second root of the polynomial `z^3 - 3*z - 1`. Similar to the previous function call, the output of this function depends on the availability of the symbolic toolbox.
- `root(z^3 - 3*z - 1, z, 3)` computes the third root of the polynomial `z^3 - 3*z - 1`. Similar to the previous function calls, the output of this function depends on the availability of the symbolic toolbox.
