Set the data types of the signals accepted by an input port
SetInputPortDataType(s, port, id)
representing the Level-2 MATLAB S-Function block.
Integer value specifying index of port to be set.
Integer value specifying ID of port's data type. Use
s.DatatypeName(id) to get the data type's name.
The Simulink® engine calls this routine to set the data
port has an
inherited data type. The data type
id is the proposed
data type for this port. Data type IDs for the built-in data types
can be found in
This method is only valid for simulation.
The S-function must check whether the specified data type is a valid data type for the specified port. If it is a valid data type, Level-2 MATLAB S-functions set the data type of the input port using the line:
s.InputPort(port).DatatypeID = id;
The S-function can also set the data types of other input and output ports if they are unknown. The engine reports an error if the S-function changes the data type of a port whose data type has been set.
If the block does not implement this routine, the engine assumes that the block accepts any data type and sets the input port data type to the specified value.
The engine calls this method until all input ports with inherited data types have their data types specified.
