DETERMINANTS of matrices used in Project 5 are computed using
Gaussian Elimination as well as MATLAB. 
The results are as follows:

File Name     Size      Determinant
--------------------------------------------
matrix.100   100x100   det = 4.354211e+20
matrix.200   200x200   det = -7.764795e+69
matrix.400   400x400   det = 3.009516e+200
matrix.800   800x800   det = -2.051189e-02
matrix.1600  1600x1600 det = 2.386961e+235
