Detailed Documentation
Numerical analysis employs numerous classical methodologies, such as polynomial least squares fitting, three-moment interpolation, Lagrange polynomial interpolation, Romberg integration, piecewise linear interpolation, and three-slope interpolation. These techniques can be effectively demonstrated using MATLAB to enhance understanding of their underlying principles and practical applications. The implementations typically involve key MATLAB functions like polyfit for polynomial fitting, custom algorithms for moment calculations in interpolation, and iterative approaches for Romberg integration refinement.
