Description

  • Fixed major bug in davidson algorithm where Gram-Schmidt was not being repeated after orthog failure.

  • Improved behavior of Truncate argument to svd and diagHermitian. Now gets set to true automatically if a truncation parameter (such as Cutoff or Maxm) is set.

  • Split tensor decomposition and MPS code into separate .cc files to help with linker limitations on Windows.

  • Removed static vectors from lapack_wrap.cc to make calls to these wrappers thread safe.

  • Fixed compilation errors and an off-by-one bug in stats.h

  • Fixed issue with using exactApplyMPO with same input and output MPS

  • Added sweepnext1 for single site sweeping algorithms

  • nmultMPO now uses a small default cutoff if none is provided
