Set the dimensions of the signals accepted by an output port
#define MDL_SET_OUTPUT_PORT_DIMENSION_INFO void mdlSetOutputPortDimensionInfo(SimStruct *S, int_T port, const DimsInfo_T *dimsInfo)
SimStruct representing an S-Function block.
Index of a port.
Structure that specifies the signal dimensions supported by port.
See ssSetInputPortDimensionInfo for a description of this structure.
The Simulink® engine calls this method with candidate dimensions dimsInfo for port. In C MEX S-functions, if the proposed dimensions are acceptable, the method sets the actual port dimensions, using ssSetOutputPortDimensionInfo. If they are unacceptable, the method generates an error via ssSetErrorStatus. This method is only valid for simulation. C MEX S-functions must enclose the method in a #if defined(MATLAB_MEX_FILE) statement.
Note This method can set the dimensions of any other input or output port whose dimensions derive from the dimensions of port.
By default, the engine calls this method only if it can fully determine the dimensionality of port from the port to which it is connected. In C MEX S-functions, if the engine cannot completely determine the dimensionality from port connectivity, it invokes mdlSetDefaultPortDimensionInfo. If an S-function can fully determine the port dimensionality from partial information, set the option SS_OPTION_ALLOW_PARTIAL_DIMENSIONS_CALL in mdlInitializeSizes, using ssSetOptions. If this option is set, the engine invokes mdlSetOutputPortDimensionInfo even if it can only partially determine the dimensionality of the output port from connectivity.
The engine calls this method until all output ports with inherited dimensions have their dimensions specified.
