rounds the elements of X to the nearest integers. For complex X, the imaginary and real parts are rounded independently.

Examples

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 
  Columns 5 through 6 
   7.0000             2.0000 + 4.0000i
