Get pointers to signals of type double connected to an input port - MATLAB ssGetInputPortRealSignalPtrs

Syntax

InputRealPtrsType ssGetInputPortRealSignalPtrs(SimStruct *S, int_T port)

Arguments

S: SimStruct representing an S-Function block.
port: Index of the port whose signal is required.

Returns

Pointers to the elements of a signal of typedoubleconnected to the input port specified by the indexport.

Description

This macro returns a pointer to an array of pointers to thereal_Tinput signal elements. The length of the array of pointers is equal to the width of the input port. The input port index starts at 0 and ends at the number of input ports minus 1.

Languages

C, C++

Example

The following example reads all input port signals.

int_T i,j; int_T nInputPorts = ssGetNumInputPorts(S); for (i = 0; i < nInputPorts; i++) { InputRealPtrsType uPtrs = ssGetInputPortRealSignalPtrs(S,i); int_T nu = ssGetInputPortWidth(S,i); for (j = 0; j < nu; j++) {SomeFunctionToUseInputSignalElement(*uPtrs[j]); } }
