NEW FOR TECHNICAL COMPUTING: MATLAB 7

Development Environment and Programming

You can now step through your M-code one section at a time, check it with M-Lint to improve speed and maintainability, and publish it to an HTML or Word document. The MATLAB language now provides nested and anonymous functions, as well as conditional breakpoints and block comments.

Integer and Single-Precision Math

MATLAB now supports integer and singleprecision arithmetic, resulting in faster computations and processing of larger data sets.

Graphics New interactive plotting and annotation tools let you create and edit your plots more quickly with no programming. Once you've created a graphic, you can automatically generate the code required to create it, enabling you to reuse it later with new data. Plots can be docked in the desktop for easier viewing of multiple graphical figures.

Data Access and External Interfaces

New data access capabilities let you easily read data from large text files and write to Excel files. MAT-files are automatically compressed when saved to disk, significantly reducing footprints and loading time.New external interfacing functions provide access to Web services and FTP sites and easier access to Java classes.

Performance

On Windows XP platforms, MATLAB can now take advantage of an additional 1 GB of memory. JIT Accelerator coverage has been extended to all numeric types and function calls.

Major Upgrades

• Communications Toolbox 3 adds multipath channel models and equalizer functions. The new BERTool GUI enables you to compare the bit error rate of your system with many proven analytical results.

• Control System Toolbox 6 has improved numerical solvers using the LAPACK and SLICOT libraries, increasing computational speed and accuracy.

• Database Toolbox 3 can retrieve additional JDBC data types, including BLOBs containing binary image data. The Visual Query Builder now includes features for the analysis and visualization of matrices, cell arrays, and structures.

• Filter Design Toolbox 3 includes support for more IIR and FIR filter methods and FDATool enhancements. VHDL and Verilog code generation are also possible via a separate product, the new Filter Design HDL Coder.

• Financial Derivatives Toolbox 3 includes the ability to perform pricing and sensitivity analysis of exotic equity options using the Cox-Ross- Rubinstein and Equal Probability models.

• Instrument Control Toolbox 2 provides support for IVI, VXIplug&play, and MATLAB instrument drivers. A new GUI enables you to identify, configure, and communicate with instruments.

• Mapping Toolbox 2 includes support for georeferenced imagery, data import from standard GIS and geospatial file formats, new map display functions, and map projection improvements.

• MATLAB Compiler 4 supports the full MATLAB language and most MATLAB based toolboxes. You can now deploy many more MATLAB applications as stand-alone executables and software components.

• Model Predictive Control Toolbox 2 is redesigned with a new GUI and better integration with Simulink.

• Optimization Toolbox 3 includes a binary integer programming solver, a simplex algorithm option for linear programming, and an improved algorithm for unconstrained optimization.

NEW FOR MODEL-BASED DESIGN: SIMULINK 6

Component-Based Modeling for Large Systems

You can now segment a model into multiple files, where each file is a separate model that can be independently managed, simulated, tested, and implemented with code generation before being incorporated back into a system model.

Data Management and Visualization

The new Model Explorer lets you navigate, create, configure, and search all data, parameters, and properties of your model, includingnew data objects for defining structure, bus, custom, and alias data type objects. You can now inject, log, and view signals without including additional source or sink blocks in your models.

Integration with Stateflow

Simulink and Stateflow integration has been improved with the addition of new unified UIs for data management and the configuration of simulation and code-generation options.

MATLAB Language Support

A new Simulink block and Stateflow function for including embedded algorithms written in a subset of the MATLAB language can be deployed with Real-Time Workshop® and Stateflow Coder. Additional functionality has been provided for creating more comprehensive M-file S-functions.
