R11.1 Blocks Will Be Removed in R2007a

The R11.1 Signal Processing Blockset blocks have been deprecated since R14SP2. In the next release, R2007a, these blocks will be completely removed from the product.

Compatibility Considerations

We strongly recommend that you replace any R11.1 blocks that you are using in your models at this time. For more information, refer to Obsolete Blocks.

New Filter Design Toolbox Block Library

A new Filter Design Toolbox block library has been added for the design and implementation of single- and multirate FIR and IIR filters. The library contains the following blocks:

• Bandpass Filter

• Bandstop Filter

• CIC Compensator

• Differentiator Filter

• Fractional Delay Filter

• Halfband Filter

• Highpass Filter

• Hilbert Filter

• Inverse Sinc Filter

• Lowpass Filter

• Nyquist Filter

More Blocks with Fixed-Point Support

Support for fixed-point data types has been added to the following blocks:

• Backward Substitution

• Forward Substitution

• LDL Factorization

• LU Factorization

From Multimedia File Block Supports Uncompressed AVI Files on UNIX

The From Multimedia File block now supports uncompressed AVI files on UNIX^® platforms. As a result, you no longer need to use separate blocks to import multimedia files if you are working on both Windows and UNIX platforms.

To Wave File and From Wave File Blocks Extended to Support More than Two Channels

The To Wave File and From Wave File blocks now support an arbitrary number of audio channels, instead of just mono and stereo.

Enabled Subsystem Support for From Wave File Block

The From Wave File block now supports enabled subsystems.

Diagnostic Output Port Added to Report a Failure to Converge

A new diagnostic output port has been added to the following blocks to report a failure to converge:

• Pseudoinverse

• Singular Value Decomposition

• SVD Solver

To make this port appear, select the Show error status port check box on the block dialog.

Compatibility Considerations

In prior releases, these blocks returned an error when the computation failed to converge. This error no longer occurs. Instead, select the Show error status port check box on the block dialog to make the error port E appear. You can then connect this port to a block such as the Simulink Assertion block to receive information about the convergence of the output.

2-D Support Added

2-D support has been added to the following blocks:

• Matrix Product

• Matrix Sum

• Maximum

• Minimum

Multichannel Support Added

Multichannel support has been added to the following blocks:

• Autocorrelation LPC

• Levinson-Durbin

• LSF/LSP to LPC Conversion

• Yule-Walker AR Estimator

• Zero Crossing

Blocks Removed from Product

The DSP Gain, DSP Sum, DSP Product, and DSP Fixed-Point Attributes blocks have been removed from the Signal Processing Blockset product.

Compatibility Considerations

You can replace any DSP Gain, DSP Sum, and DSP Product blocks in your models with Simulink Gain, Sum, and Product blocks, respectively. There is no replacement for the DSP Fixed-Point Attributes block.
