No documentation available

Matrix#upper_triangular?

Returns true if this is an upper triangular matrix.

Matrix#to_matrix

Explicit conversion to a Matrix. Returns self

Vector#to_matrix

PP::sharing_detection

Returns the sharing detection flag as a boolean value. It is false (nil) by default.

PP::sharing_detection=

Sets the sharing detection flag to b.

MatchData#named_captures

Returns a Hash using named capture.

A key of the hash is a name of the named captures. A value of the hash is a string of last successful capture of corresponding group.

m = /(?<a>.)(?<b>.)/.match("01")
m.named_captures #=> {"a" => "0", "b" => "1"}

m = /(?<a>.)(?<b>.)?/.match("0")
m.named_captures #=> {"a" => "0", "b" => nil}

m = /(?<a>.)(?<a>.)/.match("01")
m.named_captures #=> {"a" => "1"}

m = /(?<a>x)|(?<a>y)/.match("x")
m.named_captures #=> {"a" => "x"}

PrettyPrint#current_group

Returns the group most recently added to the stack.

Contrived example:

out = ""
=> ""
q = PrettyPrint.new(out)
=> #<PrettyPrint:0x82f85c0 @output="", @maxwidth=79, @newline="\n", @genspace=#<Proc:0x82f8368@/home/vbatts/.rvm/rubies/ruby-head/lib/ruby/2.0.0/prettyprint.rb:82 (lambda)>, @output_width=0, @buffer_width=0, @buffer=[], @group_stack=[#<PrettyPrint::Group:0x82f8138 @depth=0, @breakables=[], @break=false>], @group_queue=#<PrettyPrint::GroupQueue:0x82fb7c0 @queue=[[#<PrettyPrint::Group:0x82f8138 @depth=0, @breakables=[], @break=false>]]>, @indent=0>
q.group {
  q.text q.current_group.inspect
  q.text q.newline
  q.group(q.current_group.depth + 1) {
    q.text q.current_group.inspect
    q.text q.newline
    q.group(q.current_group.depth + 1) {
      q.text q.current_group.inspect
      q.text q.newline
      q.group(q.current_group.depth + 1) {
        q.text q.current_group.inspect
        q.text q.newline
      }
    }
  }
}
=> 284

Prime#prime_division

Returns the factorization of value.

For an arbitrary integer:

p_1**e_1 * p_2**e_2 * ... * p_n**e_n,

prime_division returns an array of pairs of integers:

[[p_1, e_1], [p_2, e_2], ..., [p_n, e_n]].

Each pair consists of a prime number – a prime factor – and a natural number – its exponent (multiplicity).

Parameters

value: An arbitrary integer.
generator: Optional. A pseudo-prime generator. generator.succ must return the next pseudo-prime number in ascending order. It must generate all prime numbers, but may also generate non-prime numbers, too.

Exceptions

ZeroDivisionError: when value is zero.

Example

Prime.prime_division(45)  #=> [[3, 2], [5, 1]]
3**2 * 5                  #=> 45

Proc#source_location

Returns the Ruby source filename and line number containing this proc or nil if this proc was not defined in Ruby (i.e. native).

Method#original_name

Returns the original name of the method.

class C
  def foo; end
  alias bar foo
end
C.instance_method(:bar).original_name # => :foo

Method#source_location

Returns the Ruby source filename and line number containing this method or nil if this method was not defined in Ruby (i.e. native).

UnboundMethod#original_name

Returns the original name of the method.

class C
  def foo; end
  alias bar foo
end
C.instance_method(:bar).original_name # => :foo

UnboundMethod#source_location

Returns the Ruby source filename and line number containing this method or nil if this method was not defined in Ruby (i.e. native).

Thread#thread_variables

Returns an array of the names of the thread-local variables (as Symbols).

thr = Thread.new do
  Thread.current.thread_variable_set(:cat, 'meow')
  Thread.current.thread_variable_set("dog", 'woof')
end
thr.join               #=> #<Thread:0x401b3f10 dead>
thr.thread_variables   #=> [:dog, :cat]

Note that these are not fiber local variables. Please see Thread#[] and Thread#thread_variable_get for more details.

Thread#thread_variable?

Returns true if the given string (or symbol) exists as a thread-local variable.

me = Thread.current
