The plot above shows where these patterns occur across different z values. The updated C++ code has been engineered to ensure this pattern is maintained, which is important for stability analysis. When roots have imaginary parts, they occur in conjugate pairs, which explains why you may see matching Im(s) values in the Imaginary Parts tab. """) st.markdown('

About the Matrix Analysis Dashboard

This dashboard performs two types of analyses:

  1. Eigenvalue Analysis: Computes eigenvalues of random matrices with specific structures, showing empirical and theoretical results.
  2. Im(s) vs z Analysis: Analyzes the cubic equation that arises in the theoretical analysis, showing the imaginary and real parts of the roots.

Developed using Streamlit and C++ for high-performance numerical calculations.
