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
ssSetInputPortDimensionInfo for a
description of this structure.
The Simulink® engine calls this method with candidate dimensions
port. In C MEX S-functions, if the proposed dimensions are
acceptable, the method sets the actual port dimensions, using
. If they are unacceptable, the method
generates an error via
. This method
is only valid for simulation. C MEX S-functions must enclose the method in a
This method can set the dimensions of any other input or output port whose dimensions
derive from the dimensions of
By default, the engine calls this method only if it can fully determine the
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
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.
