Computes the two-dimensional auto correlation of a sequence.
The input sequence.
This input can be a 2D array of double-precision, floating-point numbers or a 2D array of complex double-precision, floating-point numbers.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
The auto correlation of the input sequence.
Error information. The node produces this output according to standard error behavior.
This node computes two-dimensional auto-correlation using the following equation:
for i = -(M-1), ..., -1, 0, 1, ... , (M-1) and j = -(N-1), ..., -1, 0, 1, ... , (N-1)
where M is the number of rows of matrix X and N is the number of columns of matrix X. The indexed elements of X that lie outside its range are equal to zero, as shown in the following relationship:
