summary:: n-ary operator pattern
related:: Classes/Pbinop, Classes/Punop, Classes/NAryOpFunction
categories:: Streams-Patterns-Events>Patterns>Math
description::
Returns a stream that applies the n-ary operator to the stream values of the receiver, taking n-1 streams as arguments. Usually, this is the result of applying an n-ary operator (i.e. a method with more than one argument) to a pattern.
Examples of n-ary operators are: blend, linlin, linexp, explin, expexp, clip, fold, wrap.
ClassMethods::
method::new
argument::operator
operator to be applied
argument::a
a pattern (or compatible pattern input)
argument::arglist
a list of patterns (or compatible pattern inputs)
Examples::
code::
(
var a;
a = Pnaryop(\wrap, Pseries(0, 1, 12), [3, 7]);
a.asStream.all;
)
// this is the same as:
(
var a;
a = Pseries(0, 1, 12).wrap(3, 7);
a.asStream.all;
)
// the scale argument can also be a pattern:
(
var a;
a = Pnaryop(\wrap, Pseries(0, 1, 12), [Pseq([3, 4, 5], inf), Pseq([9, 7], inf)]);
a.asStream.all;
)
// common cases:
Pwhite(0, 1, inf).linexp(0, 1, 200, 1000);
Pwhite(0, 1, inf).degreeToKey([0, 1, 3, 5, 7, 9, 11], 10);
blend(Pseq([1, 2, 3], inf), Pseq([3, 2, 1, 0], inf), Pseries(0, 0.01, inf));
