Implement Matching Pursuit (MP) and Orthogonal Matching Pursuit (OMP) algorithms. b. Compute the coherence of D : µ = maxd,d0∈D|hd,d0i| c. Write a procedure that generates a vector x = Da by picking K random positions in a and sets those positions to random numbers (normal distribution). Then write a procedure that reports the error in recovering a from x by using the MP and OMP algorithms. d. Vary the level of sparsity in a (subset) of the range 1 ≤ K ≤ d. For each sparsi …
