PLUS _ _ _ _ _ _ _ _ _ _ _ _ operator

The plus operator is both an infix and prefix n-ary addition operator. It exists because of the way in which REDUCE handles such operators internally, and is not recommended for use in algebraic mode programming. plussign, which has the identical effect, should be used instead.

syntax:

plus(<expression>,<expression>{,<expression>} *) or

<expression> plus <expression> {plus <expressio n>}*

<expression> can be any valid REDUCE expression, including matrix expressions of the same dimensions.

examples:

a plus b plus c plus d; 

  A + B + C + D 


4.5 plus 10;

plus(x**2,y**2);
