If m is a non-square matrix , m.lup.det should raise Matrix::ErrDimensionMismatch, but it raises NoMethodError.

ruby -rmatrix -e 'Matrix[[0, 0]].lup.det'
C:/ruby200/lib/ruby/2.0.0/matrix/lup_decomposition.rb:80:in det': undefined method square?' for #Matrix::LUPDecomposition:0xbb4284 (NoMethodError)
from -e:1:in `'

marcandre, Is this 2.0 issue? High priority? (release blocker?)
