Recursive Least Squares Estimation for Polynomial Coefficients in y(i) = b0 + b1 * x + b2 * x^2 + ... + bn * x^n

Implementation of recursive least squares method to estimate coefficients b0, b1, ..., bn in polynomial y(i) = b0 + b1 * x + b2 * x^2 + b3 * x^3 + ... + bn * x^n, with algorithm explanation and code implementation considerations.

Wavelet Decomposition of b1 and b2 Images Using wavedec2() Function

Perform multi-level wavelet decomposition on images b1 and b2 using the wavedec2() function with 'db1' wavelet at level 3, followed by image fusion implementation.
