W' = [[2,0,0],[0,0,-1],[0,3,0]] x = [-1,3,-3]
let h = [a, b, c] W'h = [2a, -b, 3c]
W' = [[2,0,0],[0,0,-1],[0,3,0]] x = [-1,3,-3]

W' = [[2,0,0], [0, 0, -1], [0,3,0]]
x = [-1, 3, -3]
For OMP -2 number of non zero entries in h is 1
Case 1: Let h = [c,0,0][c,0,0] || x - W’h|| = (1+2c)2(1+2c)2 + 9 + 9
min value . = 18 when c = -1/2
Case 2: || x - W’h|| = (3+3c)2(3+3c)2 + 1 + 9
min value . = 10 when c = -1 and h=[0,−1,0]h=[0,-1,0]
Case 3: || x - W’h|| = (3+c)2(3+c)2 + 1 + 9
min value . = 10 when c = -3 and h=[0,0,−3]h=[0,0,-3]
Case 2 and Case 3 gives answer
