    def each
      (0...length).each do |i|
        yield get(i)
      end
    end
each_column() {|column(j)| ...}

Iterate over columns.

# File lib/jblas/mixin_enum.rb, line 50
    def each_column
      (0...columns).each do |j|
        yield column(j)
      end
    end
each_row() {|row(i)| ...}

Iterate over rows.

# File lib/jblas/mixin_enum.rb, line 43
    def each_row
      (0...rows).each do |i|
        yield row(i)
      end
    end
map(&block)

Map each element.

Returns a new matrix of the same type. This means that the block must return something which can again be stored in the matrix.

[Source]

# File lib/jblas/mixin_enum.rb, line 67
    def map(&block)
      return dup.map!(&block)
    end
map!(&block)

Map each element and store the result in the matrix.

Note that the result must be again something which can be stored in the matrix. Otherwise you should do an to_a first.

[Source]

# File lib/jblas/mixin_enum.rb, line 76
    def map!(&block)
      (0...length).each do |i|
        put(i, block.call(get(i)))
      end
      self
    end
