Y = round(X)

a = [-1.9, -0.2, 3.4, 5.6, 7.0, 2.4+3.6i]

a =
  Columns 1 through 4 
  -1.9000            -0.2000             3.4000             5.6000 
  Columns 5 through 6 
   7.0000             2.4000 + 3.6000i

round(a)

ans =
  Columns 1 through 4 
  -2.0000                  0             3.0000             6.0000
