If the inversion was performed correctly, then the multiplication of the original matrix with the inverted matrix should yield identity matrix. This is known as(a) Identity theorem(b) Safety theorem(c) Multiplication theorem(d) Inversion theoremI got this question in final exam.This intriguing question originated from Properties of Convolution Codes and Reed-Solomon Codes in division Channel Coding of Digital Communications

Answer»

The CORRECT answer is (B) Safety theorem

For explanation I would say: According to safety theorem, if the inversion is performed correctly, the multiplication of ORIGINAL matrix by INVERTED matrix will yield identity matrix.
