Wirawan Purwanto
a347ae6d47 * New module: wpylib.math.stats.array_stats, for studying statistics of 
an array (e.g., sparsity, difference, etc).
 2014-04-07 12:25:33 -04:00

b043fb3cdf * fit_func: Added support for lmfit-based minimization. 
Tested minimally in the Cr2_analysis_cbs.py workbench (routine:
  Test_MC_FPTZ_20140206).

363999badf * Added str_lstrip, str_rstrip functions for a Bourne-like substring 
stripping.

Wirawan Purwanto
839948a8da * Moved the following functions from wpylib.shell_tools to 
wpylib.file.file_utils since they are not directly related to shell:

  - file_exists_nonempty
  - is_executable_file
  - dirname2
  - relpath
  - path_split_all
  - list_dir_entries

  These are new API functions, so hopefully their changes would not
  affect many existing scripts.

* Added support for xz-compressed tar in untar() routine. Untested.

* Documentation updates.
 2014-01-16 12:31:57 -05:00
Wirawan Purwanto

  testdir() function argument.

fc0d97db1e * Parameters._flatten_(): Added workaround to avoid evaluating the 
dict values while flattening the list.
  This is critical for avoiding evaluation of the 'active' members.
 2013-04-25 16:54:36 -04:00
Wirawan Purwanto
2daca4af6e * tee_output: Allow None to be given in the `files' argument, which stands 
for a null file.

80961ed2bd * Added test7 and test8 for param_flat module. 
- test7 tests active parameters which can work OK if the search dicts are
    flatten.
  - test8 tests the _flatten_() method.
 2013-04-17 17:26:48 -04:00
Wirawan Purwanto
b326937d80 * Parameters: Now correctly implements _flatten_() method and flag. 
- The _flatten_() method should recursively flatten the parameter
    search space into a single dict.
  - The _flatten_ flag will flatten the input dicts and keyword-based
    parameter (in the __init__() method only) in the expected order of
    priority (where the first found keyword is the most overriding one)
    into a single search dict.
 2013-04-16 14:06:26 -04:00
Wirawan Purwanto
8d32c2c067 * Parameters: if _flatten_ is enabled, must flatten in reverse order to 
give the firstly mentioned dict the priority.
