Query: An efficient parallel algorithm for computing determinant of non square
  matrices   One of the most significant challenges in Computing Determinant of
Rectangular Matrices is high time complexity of its algorithm. Among all
definitions of determinant of rectangular matrices, used definition has special
features which make it more notable. But in this definition, C(n m) sub
matrices of the order m*m needed to be generated that put this problem in NP
hard class. On the other hand, any row or column reduction operation may hardly
lead to diminish the volume of calculation. Therefore, in this paper we try to
present the parallel algorithm which can decrease the time complexity of
computing the determinant of non-square matrices to O(pow(n,2)).
