Establishing a New Matrix and Matrix Order Transformation by that New Matrix

This is an original research work with new inventions which will show the Matrix Order Transformation based on Perimeter Matrix, which I invented previously. This method will be generalised for n-th term to convert a matrix of order n×n into a matrix of order 3×3 and regain the original matrix of order n×n from the resultant matrix of order 3×3. For the n-th term I named it as the Method of Determinant Block Transformation.
