DSP Blockset Release Notes

Library Reorganization

The DSP Blockset libraries have been reorganized for clarity and accessibility. The revised library hierarchy is shown below:

• DSP Sinks
• DSP Sources
• Estimation
• Linear Prediction
• Parametric Estimation
• Power Spectrum Estimation
• Filtering
• Adaptive Filters
• Filter Designs
• Filter Structures
• Multirate Filters
• Math Functions
• Math Operations
• Matrices and Linear Algebra

  Linear System Solvers

  Matrix Factorizations

  Matrix Inverses

  Matrix Operations

• Polynomial Functions
• Quantizers
• Signal Management
• Buffers
• Indexing
• Signal Attributes
• Switches and Counters
• Signal Operations
• Statistics
• Transforms

Use the Simulink Library Browser to access the blockset directly through this hierarchical library list.

As a result of the reorganization, a number of existing blocks have been moved to new locations. Table 3-2 below lists the changes.
