linkprop.m: Overhaul function for performance and Matlab compatibility.
* NEWS: Announce changes in linkprop behavior.
* linkprop.m: Redo docstring. Add more input validation. When linking, set
property values to be that of the first object in the list (missing Matlab
compatibility). Use onCleanup instead of an hggroup in order for 'clear hlink'
command to correctly unlink properties. For performance, avoid for loops in
update_prop and use set() with multiple handles. Add %!demo, %!test, and
%!error code to verify function.

Summary of important user-visible changes for version 4.2: --------------------------------------------------------- ** Interpolation function changes for Matlab compatibility The interpolation method 'cubic' is now equivalent to 'pchip' for interp1, interp2, and interp3. Previously, 'cubic' was equivalent to 'spline' for interp2. This may produce different results as 'spline' has continuous 1st and 2nd derivatives while 'pchip' only has a continuous 1st derivative. ** Integer formats used in the printf family of functions now work for 64-bit integers and are more compatible with Matlab when printing non-integer values. Now instead of truncating, Octave will switch the effective format to '%g' in the following circumstances: * the value of an integer type (int8, uint32, etc.) value exceeds the maximum for the format specifier. For '%d', the limit is intmax ('int64') and for '%u' it is intmax ('uint64'). * round(x) != x or the value is outside the range allowed by the integer format specifier. There is still one difference: Matlab switches to '%e' and Octave is currently switching to '%g'. ** linkprop has been completely re-coded for performance and Matlab compatibility. It now returns a linkprop object which must be stored in a variable for as long as the graphic objects should remain linked. To unlink properties use 'clear hlink' where hlink is the variable containing the linkprop object. ** Other new functions added in 4.2: dir_in_loadpath hgload hgsave javachk numfields ** Deprecated functions. The following functions have been deprecated in Octave 4.2 and will be removed from Octave 4.6 (or whatever version is the second major release after 4.2): bicubic find_dir_in_path nfields The following functions were deprecated in Octave 3.8 and have been removed from Octave 4.2. default_save_options java_new gen_doc_cache java_set interp1q java_unsigned_conversion isequalwithequalnans javafields java_convert_matrix javamethods java_debug re_read_readline_init_file java_get read_readline_init_file java_invoke saving_history The following keywords were deprecated in Octave 3.8 and have been removed from Octave 4.2 static The following configuration variables were deprecated in Octave 3.8 and have been removed from Octave 4.2 CC_VERSION (now GCC_VERSION) CXX_VERSION (now GXX_VERSION) The internal class <Octave_map> was deprecated in Octave 3.8 and has been removed from Octave 4.2. Replacement classes are <octave_map> (struct array) or <octave_scalar_map> for a single structure. Summary of important user-visible changes for version 4.0: --------------------------------------------------------- ** For compatibility with Matlab, the "backtrace" warning option is now enabled by default. ** The preference do_braindead_shortcircuit_evaluation is now enabled by default. ** The preference allow_noninteger_range_as_index is now enabled by default and the warning ID Octave:noninteger-range-as-index is now set to "on" by default instead of "error" by default and "on" for --traditional. ** polyeig now returns a row vector of eigenvalues rather than a matrix with the eigenvalues on the diagonal. This change was made for Matlab compatibility. ** Other new functions added in 4.0.0: validateattributes ** Deprecated functions. The following functions were deprecated in Octave 3.6 and have been removed from Octave 4.0. cut polyderiv cor shell_cmd corrcoef studentize __error_text__ sylvester_matrix error_text The following functions have been deprecated in Octave 4.0 and will be removed from Octave 4.4 (or whatever version is the second major release after 4.0): allow_noninteger_range_as_index do_braindead_shortcircuit_evaluation --------------------------------------------------------- See NEWS.3 for old news.
