4.7 _JT_ storage_ blocktridiagdiagoff_ - block-tridiagonal with diagonal off-diagonal blocks

• Status: NOT IMPLEMENTED
• Current value: 6
• Also requires:

  Variable	Meaning	Value
  ia(_JT_ idim_)	leading dimension	3
  ia(_JT_ nrows_)	number of rows	2
  ia(_JT_ blocksize_)	size of blocks	7
  ia(_JT_ blocks_)	number of blocks	8

• Description:

  In this case the B's and C's are diagonal matrices, so they are stored as n - 1 columns (each) after A_n.
