DIFFERENCE _ _ _ _ _ _ _ _ _ _ _ _ operator

The difference operator may be used as either an infix or prefix binary subtraction operator. It is identical to - as a binary operator.

syntax:

<expression> difference <expression> {difference <expression>}*

<expression> can be a number or any other valid REDUCE expression. Matrix expressions are allowed if they are of the same dimensions.

examples:

difference(10,4); 

  6 



15 difference 5 difference 2; 

  8 



a difference b; 

  A - B

The difference operator is left associative, as shown in the second example above.
