ceil - Round toward positive infinity

Syntax

B = ceil(A)

Description

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 

  Columns 5 through 6 
   7.0000        3.0000 + 4.0000i
