octave-forge-stk-2.5.1-bp153.1.23

- Update to version 2.5.1:
  * tk_dominatedhv: Workaround for Octave 4.4 issue (ticket #89)
  * Documentation fixes.
  * stk_option_set: Return option struct only if nargout > 0.

- Update to version 2.5.0
  * Required Octave version number has been raised to 3.6.0.
  * Sequential design of experiments:
  - `stk_sampcrit_akg_eval`: New function.  Computes the
    Approximate Knowledge Gradient (AKG) sampling criterion.
  - `stk_example_doe05`: Example script that demonstrates the
    use of the AKG and EQI sampling criteria for noisy
    optimization.
  - New (experimental) classes to represent sampling criterion
    objects: `stk_sampcrit_ei`, `stk_sampcrit_akg`,
    `stk_sampcrit_eqi`.
  - `stk_sampcrit_ei_eval`: Remove deprecated calling forms.
  * Design of experiments:
  - `stk_factorialdesign`: Accept one-variable `stk_dataframe`
    objects as factors and preserve column names in this case.
  - `stk_sampling_nesteddesign`: New function to create nested
    designs.
  - `stk_sampling_nestedlhs`: New function to create nested LHS
    (NLHS).
  - `stk_sampling_sobol`: Fix help text.
  * Validation of models:
  - `stk_distrib_normal_crps`: New function to compare
    observations and predictive (Gaussian) density.
  - Calling `stk_predict_leaveoneout` with no output arguments
    now automatically creates two cross-validation diagnostics
    in two subplots: prediction VS observations (left panel) and
    normalized residuals (right panel).
  - `stk_predict_leaveoneout` uses now the virtual LOO formula.
  * `stk_dataframe` and related classes
  - `stk_hrect`: Preserve column names for `stk_dataframe`
    inputs.
  - `@stk_dataframe/find`: Overload base function to support
    calling find with an stk_dataframe as first input argument.
  - `@stk_dataframe/plotmatrix`: Overload base function to
    enrich `plotmatrix` graphics with variable names when
    possible.
  * Logical functions:
  - Operations that normally return logical (`lt`, `eq`,
    `and`...) now return logical values for `stk_dataframe`
    arguments.
  - New overloaded functions for `stk_dataframe` objects:
    `isinf`, `isnan`, `isfinite`.
  * Testing array membership:
  - `@stk_dataframe/ismember`: No longer assumes `rows` flag for
    consistency with the base `ismember` function.
  - `stk_factorialdesign/ismember`: New function.  Tests
    membership for factorial designs much more efficiently than
    for plain arrays or data frames.
  * `stk_generate_samplepaths` now returns a plain numerical array instead of
    a data frame.
  * Miscellaneous:
  - `stk_plot_probdom2d`: New function to represent the
    uncertainty about a 2D Pareto front.  This function is
    currently considered experimental and should not be expected
    to produce a reliable representation of the uncertainty for
    difficult or high-dimensional optimization problems.
  - New test case: "truss3" (Koski, 1985; Das, 1997).
  - Many functions have been optimized for speed.
  - `stk_plot1d`: Handle the case where `xt` is not sorted.
  - Support old-style STK structures (with a `.a` field) has
    been removed.
