Task4_analysis.pdf has some MATLAB snippets regarding how I found an ansatz.
Task4_VQE.pdf == Task4_VQE.ipynb contain a qiskit implementation of VQE for the given matrix.
Curve shows min. eigenvalue ~ -1.
Single parameter circuit. Fancy optimization seemed unnecessary; could've use something like Newton Raphson to find minimum if I was running on IBMq backend.
tutorial notes are from the qiskit textbook
