Get the dimensions of the signal accepted by an input port
int_T *ssGetInputPortDimensions(SimStruct *S, int_T port)
S
SimStruct representing an S-Function block.
port
Index of an input 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.
