Added special-case logical-indexing function
* logical-index.h (New file) : Logical-indexing function. May be called on
octave_value types via call_bool_index
* nz-iterators.h : Add base-class nz_iterator for iterator types. Array has
template bool for whether to internally store row-col or compute on the fly
Add skip_ahead method which skips forward to the next nonzero after its
argument
Add flat_index for computing octave_idx_type index of current position (with
assertion failure in the case of overflow)
Move is_zero to separate file
* ov-base-diag.cc, ov-base-mat.cc, ov-base-sparse.cc, ov-perm.cc
(do_index_op): Add call to call_bool_index in logical-index.h
* Array.h : Move forward-declaration for array_iterator to separate header file
* dim-vector.cc (dim_max): Refers to idx-bounds.h (max_idx)
* array-iter-decl.h (New file): Header file for forward declaration of
array-iterator
* direction.h : Add constants fdirc and bdirc to avoid having to reconstruct
them
* dv-utils.h, dv-utils.cc (New files) :
Utility functions for querying and constructing dim-vectors
* idx-bounds.h (New file) :
Utility constants and functions for determining whether things will overflow
the maximum allowed bounds
* interp-idx.h (New function : to_flat_idx) : Converts row-col pair to linear
index of octave_idx_type
* is-zero.h (New file) : Function for determining whether an element is zero
* logical-index.tst : Add tests for correct return-value dimensions and large
sparse matrix behavior

GNU Octave -- a high-level language for numerical computations. Copyright (C) 1996-2013 John W. Eaton Overview -------- GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically. GNU Octave is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 3 of the License, or (at your option) any later version. GNU Octave is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the file COPYING for more details. Availability ------------ The latest released version of Octave is always available via anonymous ftp from ftp.gnu.org and its many mirror sites around the world. You may also find links to binary distributions at http://www.octave.org/download.html. The current development sources may be found on Savannah (http://savannah.gnu.org/projects/octave) under the Source Code tab. Installation ------------ Octave requires approximately 1.4 GB of disk storage to unpack and compile from source (significantly less, 400 MB, if you don't compile with debugging symbols). Once installed, Octave requires approximately 350MB of disk space (again, considerably less, 70 MB, if you don't build shared libraries or the binaries and libraries do not include debugging symbols). To compile Octave, you will need a recent version of GNU Make. You will also need a recent version of g++ or another ANSI C++ compiler. You will also need a Fortran 77 compiler or f2c. If you use f2c, you will need a script like fort77 that works like a normal Fortran compiler by combining f2c with your C compiler in a single script. YOU MUST HAVE GNU MAKE TO COMPILE OCTAVE. Octave's Makefiles use features of GNU Make that are not present in other versions of make. GNU Make is very portable and easy to install. See the notes in the files INSTALL and the system-specific README files in the etc directory of the Octave source distribution for more specific installation instructions. Bugs and Patches ---------------- The file BUGS explains the recommended procedure for reporting bugs or contributing patches. Documentation ------------- Octave's manual has been revised for version 3.4, but it is lagging a bit behind the development of the software. In particular, there is currently no complete documentation of the C++ class libraries. If you notice omissions or inconsistencies, please report them on the bug tracker at http://bugs.octave.org. Specific suggestions for ways to improve Octave and its documentation are always welcome. Reports with patches are even more welcome. Additional Information ---------------------- Up to date information about Octave is available on the WWW at the URL http://www.octave.org, including archives of the help, bug, and maintainers mailing lists.
