B = ceil(A) rounds the elements of A to the nearest integers greater than or equal to A. For complex A, the imaginary and real parts are rounded independently.

Examples

• a = [-1.9, -0.2, 3.4, 5.6, 7, 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
  
  ceil(a)
  
  ans =
    Columns 1 through 4 
    -1.0000            0             4.0000             6.0000
