Matrix Inversion

Given a square matrix the program calculates the inverse matrix as well as the order, the rank and the determinant of the matrix.

Example:

Matrix :        
¯¯¯¯¯¯¯¯
  ⎧ 1  0  2 ⎫
  ⎪ 0  1  0 ⎪
  ⎩ 3  0  1 ⎭

Inverse Matrix :
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
  ⎧-0,2  0  0,4 ⎫
  ⎪   0  1    0 ⎪
  ⎩ 0,6  0 -0,2 ⎭

Order = 3,  Rank = 3,  Determinant = -5
