random
Represents a random element in a container.
Syntax
-
random(X)-
Xis any container
-
The returned value is an lvalue unless X is a set.
Description
If X is any container, then random(X) is a randomly chosen element of it.
X may be a vector, a matrix, a list, a set, a structure, a string, or a pixmap.
Unless S is a set, random(X) is an lvalue, so it may be assigned to. The right hand side must be an object of suitable type. For instance, if X is a real vector, the value must be a real number; if X is a string, the value must be a character.
