SWAP(A,B) puts the contents of variable A into variable B and vice versa. You can use either function syntax 'swap(A,B)' or command syntax 'swap A B'.

Example:
A = 1:4 ; B = 'Hello' ;
swap(A,B) ;
A % -> Hello
B % -> 1 2 3 4
swap A B ; % and back again ...

SWAP(A,B) is a convenient easy short-cut for other (series of) commands that have the same effect,e.g.,

temp=A ; A=B ; B=temp ; clear temp ;
[B,A] = deal(A,B) ;

The advantage over these two methods is that using SWAP one does not have to declare intermediate variables or worry about output.
