PERMPOS
PERMPOS - all possible permutations of M values in N positions more>>
PERMPOS is a convenient mathematical tool which contains all possible permutations of M values in N positions. B = PERMPOS(M,N) where M and N are non-negative integers produces a logical (N!/M!(N-M)!)-by-N matrix in which each row contains a unique permation of M trues and (N-M) falses. Note that each column will hence contain (N-1) trues.
B = PERMPOS(V,N) where V is a vector of length M produces a matrix where each row a contains the values of V in preserved order, but uniquely permuted at the N columns. The remaining positions are zero.
Examples:
permpos(2,4) % ->
% 1 1 0 0
% 1 0 1 0
% 1 0 0 1
% 0 1 1 0
% 0 1 0 1
% 0 0 1 1
permpos([-4 9 3],4) % >

% -4 9 0 3
% -4 0 9 3

Asymptote
Asymptote is a powerful descriptive vector graphics language that provides a natural coordinate-based framework for technical drawing. more>> Asymptote offers you a wonderful utility which provides a natural coordinate-based framework for technical drawing. Labels and equations are typeset with LaTeX, for high-quality PostScript output. A major advantage of Asymptote over other graphics packages is that it is a programming language, as opposed to just a graphics program.
Major Features:
- Provides a portable standard for typesetting mathematical figures, just as TeX/LaTeX has become the standard for typesetting equations.
- Inspired by MetaPost, with a much cleaner, powerful C -like programming syntax and floating-point numerics;
- Runs on all major platforms (UNIX, MacOS, Microsoft Windows);
- Mathematically oriented (e.g. rotation of vectors by complex multiplication);
- LaTeX typesetting of labels (for document consistency);
- Uses simplex method and deferred drawing to solve overall size constraint issues between fixed-sized objects (labels and arrowheads) and objects that should scale with figure size;
- Fully generalizes MetaPost path construction algorithms to three dimensions;
- Compiles commands into virtual machine code for speed without sacrificing portability;
- High-level graphics commands are implemented in the Asymptote language itself, allowing them to be easily tailored to specific applications.
yEd Graph Editor 3.1.2.1
This is a very powerful graph editor that can be used to generate drawings and to apply automatic layouts to a range of different diagrams and networks. more>>
Major Features:
- Several highly sophisticated layout algorithms have been implemented and they can be used either to automatically arrange the items or to support the user when undertaking a manual layout.
- Enables users to create groups of nodes, which can be visualized and nested to virtually any degree.
- Ability to automatically assign label positions. This will enable the user to easily build improved diagrams, with each label clearly readable.
- An intuitive user interface that complies with modern design guidelines for applications.
- Build, modify, and visualize graph structures in an effective and efficient manner. They can be loaded and saved using a variety of different file formats.
- For exporting graph structures, yEd offers file formats for image and vector graphics export
- All of the image export formats can be fully customized to meet your unique needs.
- The editor supports the complete set of graphical attributes necessary for effective graph visualization.
Enhancements: Improvements: Problems during the setup for reusing an already running yEd application instance are handled more gracefully. If the setup fails, yEd starts up as in the pre-3.1.2 days.
Requirements: Java Runtime Environment (JRE)

INSERTROWS
INSERTROWS - Insert rows into a matrix at specific locations more>> INSERTROWS provides you a powerful mathematical tool which is able to insert rows into a matrix at specific locations.
C = INSERTROWS(A,B,IND) inserts the rows of matrix B into the matrix A at the positions IND. Row k of matrix B will be inserted after position IND(k)in the matrix A. If A is a N-by-X matrix and B is a M-by-X matrix, C will be a (N M)-by-X matrix. IND can contain non-integers.
If B is a 1-by-N matrix, B will be inserted for each insertion position specified by IND. If IND is a single value, the whole matrix B will be inserted at that position. If B is a single value, B is expanded to a row vector. In all other cases, the number of elements in IND should be equal to the number of rows in B, and the number of columns, planes etc should be the same for both matrices A and B. If any of the inputs are empty, C will return A.
Examples:
% the size of A,B, and IND all match
C = insertrows(rand(5,2),zeros(2,2),[1.5 3])
% the row vector B is inserted twice
C = insertrows(ones(4,3),1:3,[1 Inf])
% matrix B is expanded to a row vector and inserted twice (as in 2)
C = insertrows(ones(5,3),999,[2 4])
% the whole matrix B is inserted once
C = insertrows(ones(5,3),zeros(2,3),2)
[C, RA, RB] = INSERTROWS(...) will return the row indices RA and RB for which C
corresponds to the rows of either A and B.
[c,ra,rb] = insertrows([1:4].,99,[0 3]) ;
c. % -> [99 1 2 3 99 4] ;
c(ra). % -> [1 2 3 4] ;
c(rb). % -> [99 99] ;
To insert columns, planes, etc., you can permute the inputs and ipermute the result.
A = ones(4,3) ; B = zeros(4,1) ;
C = insertrows(permute(A,[2 1]), permute(B,[2 1]),1) ;
C = ipermute(C,[2 1]) ;

TOAD 0.64.0
TOAD is a C graphical user interface library. more>>
TOAD 0.64.0 is a script featuring a C graphical user interface. It provides some standard features found in other GUI libraries.
Major Features:
- Model-View Architecture
- UTF-8 text encoding
- True color and color dithering on 4 to 8 bit display depths
- ISO C Template based Signal & Slot style callbacks
- Signal & Slots is the name of the callback technique in the Qt C GUI library which requires an additional pre-processor while TOAD achieves the same with C templates.
- Experience shows that keeping track of callbacks in complex applications is too complicated so a new idea is to introduce a central database of callbacks.
- Closures Well not real closures but closure alike constructs for callbacks. The current implementation uses pre-processor macros but using C templates by provide some advantages in the future.
- Platform independent font specification via font config (for both X11 and FreeType fonts)
- Plugable Layout Managers
- 2D vector graphic editor
- Postscript, PDF and SVG output (through the Cairo graphics library)
- high quality UTF-8 text rendering (through Gtks Pango library)
- Minimal HTML Viewer for Online Documentation
- The following features are unique:
- Decoupled Menubar
- Methods and the menubar/toolbar are connected automatically over the window hierarchy. This not only simplifies the creation of menubars but also allows automatic handling of different menu styles like the single menubar under MacOS X or the typical one menubar per window under X11.
- Decoupled Undo Management Undo objects and undo-mangers/menu-bars are connected automatically over the window hierarchy.
- Run-time Layout Editor Layouts of dialogs, menu-bars, form-layouts, etc. can be configured at run-time.
Requirements:
- Binutils 2.9.1 or later
- glibc 2.1 or later
- X Window System Version 11 Release 6 or later
- zlib 1.1.1
- libpng 1.0.1
