To create a matrix of variables like x, y and z, the “syms” function can be used. It is utilized to create symbolic scalar variables and functions. For more information about the “syms” function, you can refer to the following documentation:
Now, we can create a matrix with all the variables defined using “syms”, and then, to compute their eigenvalues, we can use “eig” function. The documentation for the “eig” function can be found as below:
You can refer to the following sample code for better understanding.
% Define the variables
syms x y z
% Define the symbolic matrix
A = [x, y, z;
y, z, x;
z, x, y];
% Compute the eigenvalues
eigenvalues = eig(A);
% Display the eigenvalues
disp('Eigenvalues of the matrix:');
disp(eigenvalues);
This will provide the output as below:
