93a89d2606 * Created array indexer for "upper diagonal" indexing mode. 
Apparently I was able to create the non-iterative version of UDdec (1-based
  indices).

47f6bced79 * wpylib.math.linalg: Added initial module for linear-algebra convenience 
functions, objects, and submodules.

6181d5588d * The sign of the scalar prefactor should not enter the uncertainty 
(err) field!

dbd36e0f1f * Added division of errorbar by a scalar. 2010-12-01 17:11:46 +00:00

bceef1e601 * Adding more methods for fitting: fmin (simplex minimization). 
I still have hard time making fitting routine work for me.
  But at least this one works for simple SHO fitting.

428b481b87 * Added initial support for errorbar object, which includes 
compression-to-string (ad hoc implementation is written in C++ with the
  help of my cp.inc library, unfortunately).

yet.

733c518735 * Added: density refitter onto a different FFT grid and/or supercell size 
(expansion to a larger supercell).
