Write a MATLAB function [p, z] = proj(A,b) that computes the projection of b onto the Column Space of an m × n matrix A. Your program should allow for the possibility that the columns of A are not linearly independent. In order for the program to work, you will need to create a basis for Col A.

For any Gaussian Integer z ∈ ℤ[i] with z = a+bi , define N(z) =a2 + b2. Using the division algorithm for the Gaussian Integers, we have show that there is at least one pair of Gaussian integers q and r such that w = qz + r with N(r) < N(z). (a) Assuming z does not divide w, show that there are always two such pairs. (b) Fine Gaussian integers z and w such that there are four pairs...

Define the following function f(n) = 5(2^n)-(2^(n-1)), n ≥ 1. Write a recursive definition for the function f(n)? Consider the following recurrence: an= 2an-1 + 3 (where a1 = 1). Compute the values of an for n ≤ 5. Find a solution for the recurrence definition and validate its correctness. Consider the following recurrence: an=2an-1 +an-1an-2 (where a1 = 1). Compute the values of an for n ≤ 5.

2. Define a function max_n(arr, n) that takes in an array and an integer as arguments. Your function will then return the n largest values from that array as an array containing n elements. It is safe to assume that arr will have at least n elements. The resulting array should have the largest number on the end and the smallest number at the beginning. For Example: max_n(np.array([1,2,3,4,5]), 3) returns np.array([3,4,5]) max_n(np.array([10,9,8,7,6,5]), 4) returns np.array([7,8,9,10]) max_n(np.array([1,1,1]), 2) returns np.array([1,1])
