See if using diag(eigenvalues) as the ‘A’ matrix will produce the desired result (along with the other matrices) using the Control System Toolbox ss function.
I would try that first.

Hello,
I notice your interest in constructing a 'State-space model' from eigenvalues and eigenvectors in MATLAB.
You can try using the 'diag(eigenvalues)' to construct the matrix 'A' and spcify the other state-space matrices 'B', 'C', 'D' (if you have them;if not, they can be identity matrices or zero matrices depending on the system).
Finally, you create the state-space model using the "ss" function.
Here is MATLAB code that helps you in creating a state-space model considering some sample set of eigenvalues and eigenvectors, assuming we are working with linearly independent eigenvectors :
% Given eigenvalues and eigenvectors
eigenvalues = [-1, -2];
eigenvectors = [1, 1; 1, -1];
% Construct A matrix
A = eigenvectors * diag(eigenvalues) / eigenvectors;
% Define B, C, and D matrices
B = [1; 0];
C = [1, 0];
D = 0;
% Create state space model
sys = ss(A, B, C, D);
You can also refer to the following MathWorks Documentation to know more about the
Hope this will help.
