I implemented standard numerical methods from scratch while self-studying. The course used was Numerical Analysis for Engineering Students
- Root finding: Bisection, Newton, Secant
- Interpolation: Lagrange, Newton forms
- Integration: Trapezoidal, Simpson’s
- Linear systems: Gaussian elimination, LU
- ODEs: Euler, RK methods
- No libraries. Just algorithms.
- Emphasis on understanding and correctness.
