Get the dimensions of the signal accepted by an input port
int_T *ssGetInputPortDimensions(SimStruct *S, int_T port)
A pointer (int_T *) to an array of integers. The array contains elements with the value DYNAMICALLY_SIZED (-1) when the size of a dimension is unknown.
Use to obtain the dimensions of the signal accepted by the input port with index port, e.g., [4 2] for a 4-by-2 matrix array. The size of the dimensions array is equal to the number of signal dimensions accepted by the port, e.g., 1 for a vector signal or 2 for a matrix signal.
