AI Analysis
●MidCozyBig Brain
Python wrapper for mpmath eigenvalues when numpy.roots loses precision on ill-conditioned polynomials.
Strengths
- •Handles Wilkinson's Catastrophe with configurable precision up to hundreds of digits.
- •Residual checks validate numerical accuracy for every single computed root automatically.
- •Modular code separates matrix construction, eigenvalue solving, and complex plotting logic.
Weaknesses
- •Competes with established libraries like numpy, scipy, and Julia built-ins.
- •CLI input loop is basic compared to standard argument parsing libraries.
