Orthogonal Matching Pursuit algorithm

Improved version of MP that orthogonalizes selected atoms, ensuring monotonic decrease in residual energy and better reconstruction.

§Arguments

  • signal - Input signal to decompose
  • dictionary - Dictionary of atoms
  • max_iterations - Maximum number of iterations
  • tolerance - Stop when residual energy drops below this threshold

§Returns

Sparse decomposition result
