- Update to version 1.6.0:
* Build fixes for Octave 5.1 and some bug fixes.
* With Octave from version 5.1 on, a parallel cluster established
with package `parallel' can be used for computation of gradients
with option `parallel_net'.
* Compatibility frontend `fmincon' has been added.
* `lsqnonlin' and `lsqcurvefit' now accept a problem structure as
single argument for compatibility.
* LinearRegression:
- Corrected errors in computing variances of data and
parameters.
- Erroneous documentation of the 2nd output (`e_var',
variances of data) has been fixed.
- The 5th output (previously `y_var'), which was erroneously
documented as the variances of dependent variables, has been
replaced by `fit_var', the variances of computed function
values.
* Removed deprecated function `samin'. The functionality is
available with the `samin' backend of function `nonlin_min'.
- Drop add_missing_iostream_include.patch: fixed in upstream
sources.
