int_T ssSetInputPortMatrixDimensions(SimStruct *S, int_T port, int_T m, int_T n)
SimStruct representing an S-Function block.
Index of an input port.
Row dimension of matrix signals accepted by port or DYNAMICALLY_SIZED.
1 if successful; otherwise, 0.
Use this function to specify that port accepts an m-by-n matrix signal. If either dimension is DYNAMICALLY_SIZED, the other must be DYNAMICALLY_SIZED or 1. If either dimension is dynamically sized, the S-function must provide mdlSetInputPortDimensionInfo and mdlSetDefaultPortDimensionInfo methods to enable the signal dimensions to be set correctly during signal propagation.
C, C++
The following example specifies that input port 0 accepts 2-by-2 matrix signals.
ssSetInputPortMatrixDimensions(S, 0, 2, 2);
See the S-function matlabroot/toolbox/simulink/simdemos/simfeatures/src/sfun_frmunbuff.c used in sfcndemo_frame.mdl for a complete example that uses this function. Running this model requires a Signal Processing Blockset license.
