7:00 – 4:00 VTX

• Read a little more of the BitCoin article. Nice description of the blockchain.
• Generated a fresh Excel matrix of codes and papers. I excluded the ‘meta’ codes (Definitions, Methods, etc) and all the papers that have zero quotes
• Duke Ellington & His Orchestra make great coding music.
• Installed new Java
• Well drat. I can’t increase the size of an existing matrix. Will have to return a new one.
• Yay!

• Need to set Identity and other housekeeping.
• Added ‘normalizeByMatrix that sets the entire matrix on a unit scale
• Need to have a calcRank function that squares and normalizes until the difference between output eigenvectors are below a certain threshold or a limit of iterations. Done?
