New features and changes introduced in this version are:

New System Objects Provide Signal Processing Algorithms for use in MATLAB

System objects are algorithms that provide stream processing, fixed-point modeling, and code generation capabilities for use in MATLAB programs. These new objects allow you to use signal processing algorithms in MATLAB, providing the same parameters, numerics and performance as corresponding Signal Processing Blockset™ blocks. System objects can also be used in Simulink models via the Embedded MATLAB^® Function block.

New Time Scope Block

This release adds a new Time Scope block to the Signal Processing Blockset Sinks library. This new block enables you to visualize real-valued floating-point and fixed-point signals in the time domain.

The new Time Scope block offers a subset of the functionality provided by the Simulink Scope block, as well as some new and improved features. The new and improved features include:

Simulation Control — You can start, stop, pause, and single-step model simulation directly from the Time Scope.
Line Property Editing — You can edit the line properties for signals displayed in the Time Scope.
New Plot Navigation Tool – Provides you with enhanced axes scaling and zooming capabilities.
Support for Frame-Based Signals — You can visualize frame-based signals using the new Time Scope block.

Compatibility Considerations

In R2009b and earlier releases, the Time Scope block in the Signal Processing Blockset Sinks library was an implementation of the Simulink Scope block.

There are no compatibility considerations for existing models. However, using the add_block command to put a Time Scope block from the Signal Processing Blockset Sinks library into your model, may result in an incompatibility. If you have any scripts that use add_block('dspsnks/Time Scope',...), you have two options:

To ensure the old behavior and continue to use the Simulink Scope block in your models, change your add_block command to the following:
```
add_block('simulink/Sinks/Scope', ...)
```
To use the new Signal Processing Blockset Time Scope block in your models, you can continue to use the add_block('dspsnks/Time Scope',...) command. However, because you cannot set the parameters of the Time Scope block from the command line, you may have to modify your code. If you previously configured any block parameters within the add_block command, you must remove those property name/property value pairs from the command before proceeding.

New UDP Send and UDP Receive Blocks

This release adds a new UDP Send block to the Signal Processing Sinks library, and a new UDP Receive block to the Signal Processing Sources library. You can use these new blocks to send and receive User Datagram Protocol (UDP) messages in your Simulink model.

Filtering Library Name Changes

The following Filtering libraries have new names in the Simulink Help Browser in R2010a.

Library	R2009b Library Name	R2010a Library Name
dspfdesign	Filter Design Toolbox	Filter Designs
dsparch4	Filter Designs	Filter Implementations

Ability to Use Some Filter Designs Library Blocks Without a Filter Design Toolbox License

You can now edit the parameter settings of some blocks in the Filtering > Filter Designs library (previously, called the Filter Design Toolbox library) without a Filter Design Toolbox™ license. As in previous releases, you do not need a Filter Design Toolbox license to run models that contain blocks from the Filter Designs library. With this change, the blocks in the Filter Designs library now fall into two categories of licensing requirements:

Blocks that allow you to edit some parameter settings without a Filter Design Toolbox license. For full functionality, these blocks still require a Filter Design Toolbox license. This category consists of the following blocks:
Blocks that you can use only in their default configuration when you do not have a Filter Design Toolbox license. To change any of the parameter settings on these blocks, you must have a Filter Design Toolbox license. This category consists of the following blocks:

Data Type Assistant and Ability to Specify Design Minimums and Maximums Added to More Fixed-Point Blocks

The following blocks now offer a Data Type Assistant to help you specify fixed-point data types on the block mask. Additionally, you can now enable simulation range checking for certain data types on these blocks. To do so, specify appropriate minimum and maximum values on the block dialog box. The blocks that support these features in R2010a are:

For more information on these features, see the following sections in the Simulink documentation:

Data Types Pane Replaces the Data Type Attributes and Fixed-Point Panes on Fixed-Point Blocks

In previous releases, some fixed-point blocks had a Data type attributes pane, and others had a Fixed-point pane. The functionality of these panes remains the same, but the pane now appears as the Data Types pane on all fixed-point Signal Processing Blockset blocks.

Signal Processing Blockset Support for the For Each Subsystem

You can use the following Signal Processing Blockset blocks in the Simulink For Each subsystem:

Support for Variable-Size Signals Added to the Window Function Block

The Window Function block now supports variable-size signals. See Working with Variable-Size Signals in the Simulink documentation for more information.

New Fixed-Point Parametric Audio Equalizer Demo

This release adds a new demo, Using the Fixed-Point Advisor to Convert a Parametric Audio Equalizer to Fixed Point, to the Fixed Point category of Signal Processing Blockset demos. This demo shows you how to use the Fixed-Point Advisor to convert the existing Parametric Audio Equalizer demo to fixed point.
