Bug #7777

wrong use of "Raise" method in matrix.rb
Description
=begin
"Raise" method added by e2mmap library shows customized error messages according to pre-registered formats:
$ irb
irb(main):001:0> require 'matrix'
=> true
irb(main):002:0> Matrix.Raise ArgumentError, 2, 3 rescue $!
=> #<ArgumentError: Wrong # of arguments(2 for 3)>
However it's not needed if we make messages by hand.
irb(main):003:0> Matrix.Raise ArgumentError, "One size must be 0"
ArgumentError: invalid value for Integer(): "One size must be 0"
