Set the dimensions of the signals accepted by an input port
#define MDL_SET_INPUT_PORT_DIMENSION_INFO void mdlSetInputPortDimensionInfo(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 the port.
a description of this structure.
The Simulink® engine calls this method during dimension
propagation with candidate dimensions
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. A C MEX S-function
must enclose the method in a
#if defined(MATLAB_MEX_FILE) statement.
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 dimensionality of
port from the port
to which it is connected. For C MEX S-functions, if the engine cannot
completely determine the dimensionality from port connectivity, it
If an S-function can fully determine the port dimensionality from
partial information, set the option

the engine invokes
if it can only partially determine the dimensionality of the input
port from connectivity.
The engine calls this method until all input ports with inherited dimensions have their dimensions specified.
