  Test compressed_solve(), which seeks a solution of an
  underdetermined linear system A*x=b, with the maximum
  number of zero entries in x.

  matrix A:
array([[ 87, 190, 118, 140, 101],
       [ 72, 170,  90, 135, 104],
       [ 12,  31,  14,  25,  20]])

  right hand side b:
array([ 5, 10,  8])

  compressed solve x1:
array([ 0.        ,  5.56756757, -3.31081081, -4.72972973,  0.        ])

  np.linalg.lstsq() x2:
