Do not use signals with more than 32 dimensions. Multidimensional Signals in Simulink Blocks The following blocks were updated to support multidimensional signals. See "Signal Dimensions" in the Simulink documentation for further details. · Abs · Assignment · Bitwise Operator · Bus Assignment · Bus Creator · Bus Selector · Compare to Constant · Compare to Zero · Complex to Magnitude-Angle · Complex to Real-Imag · Concatenate · Constant · Data Store Memory · Data Store Read · Data Store Write · Data Type Conversion · Embedded MATLAB Function · Environment Controller 155 Simulink® Release Notes · From · From Workspace · Gain (only if the Multiplication parameter specifies Element-wise(K*u)) · Goto · Ground · IC · Inport · Level-2 M-File S-Function · Logical Operator · Magnitude-Angle to Complex · Manual Switch · Math Function (no multidimensional signal support for the transpose and hermitian functions) · Memory · Merge · MinMax · Model · Multiport Switch · Outport · Product, Product of Elements -- only if the Multiplication parameter specifies Element-wise · Probe · Random Number · Rate Transition · Real-Imag to Complex · Relational Operator · Reshape 156 Version 6. 6 (R2007a) Simulink® Software · Scope, Floating Scope · Selector · S-Function · Signal Conversion · Signal Specification · Slider Gain · Squeeze · Subsystem, Atomic Subsystem, CodeReuse Subsystem · Add, Subtract, Sum, Sum of Elements -- along specified dimension · Switch · Terminator · To Workspace · Trigonometric Function · Unary Minus · Uniform Random Number · Unit Delay · Width The Block Support Table does not list which blocks support multidimensional signals. 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. See the Selector block Sample time parameter for details. [. . . ] The first function outputs the transpose of the input matrix. The second function outputs the complex conjugate transpose (Hermitian) of the input matrix. 276 Version 4. 0 (R12) Simulink® Software Reshape Block Simulink 4. 0 introduces the Reshape block, which changes the dimensionality of its input signals, based on an Output dimensionality parameter that you specify. For example, the block can change an n-element vector to a 1-by-N or N-by-1 matrix signal and vice versa. You can find the Reshape block in the Simulink Signals & Systems library. Multiplexing Matrix Signals The Simulink Mux, Demux, and Bus Selector blocks have been enhanced to support multiplexing of matrix signals. Function Call Iteration Parameter Simulink 4. 0 adds a Number of iterations parameter to the Function Call Generator block. [. . . ]
