Generally I wished to have a similar notation as in C  or java (logical) ? a

Is there a built in function to have such conditionals ?

Example:

--> format(6)
--> a = rand(3,4)
 a  =
   0.362   0.483   0.502   0.633
   0.292   0.332   0.437   0.405
   0.566   0.594   0.269   0.918

--> c = a< 0.5
 c  =
  T T F F
  T T T T
  F F T F

--> a(c) = 0
 a  =
   0.  0.  0.502   0.633
   0.  0.  0.  0.
   0.566   0.594   0.  0.918

Hello Frieder,

max(A,B) does it:
--> max(A,B)
 ans  =
   3.
   3.
   2.

Hello, 

I have to matrices: A = [ 1 ; 2 ; 2 ] B = [ 3 ; 3 ; 1 ] 

I looking for get matric with having only the larger Elemtns: 

C = [ 3 ; 3 ; 2 ] 
Is there function to make to apply functions to eacth element. 

C = [ if A .> B then A else B] elemtwise. 

A for loop is to slow. 

Thanks a lot. 

Cheers 
Frieder
