## Find code matrix =======================================================
# This is main part to find the parity matrix.
- # For example, find SECDED for 4bit message is to find 3x4 matrix as below
- # | 1 0 0 0 x x x |
- # | 0 1 0 0 x x x |
- # | 0 0 1 0 x x x |
- # | 0 0 0 1 x x x |
+ # For example, find SECDED for 4bit message is to find 4x4 matrix as below
+ # | 1 0 0 0 x x x x |
+ # | 0 1 0 0 x x x x |
+ # | 0 0 1 0 x x x x |
+ # | 0 0 0 1 x x x x |
# Then message _k_ X matrix_code ==> original message with parity
#
# Make a row to have even number of 1 including the I matrix.
