To see if a block supports multidimensional signals, check for the entry Multidimensionalized in the Characteristics table of a block. Multidimensional Signals in S-Functions To use multidimensional signals in S-functions, you must use the new SimStruct function, ssAllowSignalsWithMoreThan2D. Multidimensional Signals in Level-2 M-File S-Functions To use multidimensional signals in Level-2 M-file S-functions, you must set the new Simulink. MSFcnRunTimeBlock property, AllowSignalsWithMoreThan2D. 157 Simulink® Release Notes New Block Parameters This release introduces the following common block parameters. · PreCopyFcn: Allows you to assign a function to call before the block is copied. See "Block Callback Parameters" in the Simulink documentation for details. · PreDeleteFcn: Allows you to assign a function to call before the block is deleted. See "Block Callback Parameters" in the Simulink documentation for details. · StaticLinkStatus: Allows you to obtain the link status of a block without updating out-of-date reference blocks See "Determining Link Status" in the Simulink documentation for details. GNU Compiler Upgrade This release upgrades the GNU® compiler to GCC 4. 0. 3 on Mac® platforms and GCC 4. 1. 1 on Linux platforms. The Fortran runtime libraries for the previous GCC 3. x versions are no longer included with MATLAB. Compatibility Considerations C, C++, or Fortran MEX-files built with the previous 3. x version of the GCC compiler are not guaranteed to load in this release. Rebuild the source code for these S-functions using the new version of the GCC compiler. Changes to Concatenate Block This release includes the following changes to the Concatenate block: · Its Mode parameter provides two settings, namely, Vector and Multidimensional array. · Its parameter dialog box contains a new option, Concatenate dimension, specifying the output dimension along which to concatenate the input arrays. · The block displays a new icon when its Mode parameter is set to Multidimensional array. 158 Version 6. 6 (R2007a) Simulink® Software This release updates Concatenate blocks when loading models created in previous releases. Changes to Assignment Block This release includes the following changes to the Assignment block: · Enter the number of dimensions in the Number of output dimensions parameter, then configure the input and output with the Index Option, Index, and Output Size parameters. · The parameter dialog box has the following new parameters: - Number of output dimensions Index Option Index Output Size · The Initialize output (Y) parameter replaces Output (Y) and has renamed options. · The Action if any output element is not assigned parameter replaces Diagnostic if not all required dimensions populated. · The block displays a new icon depending on the value of Number of input dimensions and the Index Option settings. The following parameters are obsolete: · Input type · Use index as start value · Source of element indices · Elements · Source of row indices · Rows · Source of column indices · Columns 159 Simulink® Release Notes · Output dimensions This release updates Assignment blocks when loading models created in previous releases. Changes to Selector Block This release includes the following changes to the Selector block: · Enter the number of dimensions in the Number of input dimensions parameter, then configure the input and output with the Index Option, Index, and Output Size parameters. · The parameter dialog box has the following new parameters: - Number of input dimensions Index Option Index Output Size · The behavior of the Sample time parameter has changed. · The block displays a new icon depending on the value of Number of input dimensions and the Index Option settings.

Improved Model Advisor Navigation and Display This release improves the Model Advisor graphical user interface (GUI) for navigating lists of checks and viewing the status of completed checks. While Model Advisor functionality and content are largely unchanged from R2006b, the Model Advisor checks display and are navigated differently than in previous versions, and the generated Model Advisor report, if requested, displays in a MATLAB web browser window that is separate from the Model Advisor GUI. [. . . ] See "Working with Signals" in the Simulink documentation for more information. Simulink Data Objects Simulink data objects allow a model to capture user-defined information about parameters and signals, such as minimum and maximum values, units, and so on (see "Working with Data Objects" in the Simulink documentation). Block Execution Order Simulink software now optionally displays the execution order of each block on the model's block diagram (see "Displaying Block Execution Order" in the Simulink documentation). 275 Simulink® Release Notes Simulink Debugger This section describes enhancements to the Simulink debugger. GUI Debugger Interface Simulink 4. 0 introduces a graphical user interface (GUI) for the Simulink Debugger. For more information, see "Simulink Debugger" in the Simulink documentation. Block Library This section describes enhancements to the Simulink block libraries. Product Block The Product block now supports both element-by-element and matrix multiplication and inversion of inputs. The block's parameter dialog includes a new Multiplication parameter that allows you to specify whether the block should multiply or invert inputs element-by-element or matrix-by-matrix. Gain Block The Gain block now supports matrix as well as element-wise multiplication of the input signal by a gain factor. The block's parameter dialog includes a new Multiplication parameter that allows you to choose the following options: · K. *u (element-wise product) · K*u (matrix product with the gain as the left operand) · u*K (matrix product with the gain as the right operand) Math Function Block The Math Function block adds two new matrix-specific functions: transpose and Hermitian.
