Matrix
# each(which = :all) {|e| . . . } -> self (6002.0) -
行列の各要素を引数としてブロックを呼び出します。
...:lower 対角成分とそれより下側の部分
* :upper対角成分とそれより上側の部分
* :strict_lower 対角成分の下側
* :strict_upper 対角成分の上側
ブロックを省略した場合、 Enumerator を返します。
//emlist[例][ruby]{
require 'matrix'
Matrix[ [1......,2], [3,4] ].each { |e| puts e }
# => prints the numbers 1 to 4
Matrix[ [1,2], [3,4] ].each(:strict_lower).to_a # => [3]
//}
@param which どの要素に対してブロックを呼び出すのかを Symbol で指定します
