Homework Statement
Describe how to create a coding matrix A so that A-1
has no fractions
The answer is Multiply a few type III matrices together, so that det A = 1
What I put is to just use an upper triangular matrix, since the det of an upper triangular matrix is 1 and you have to do row operations in order to get the matrix into an upper triangular form.
Not sure if answer would be accepted as partially correct.
