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.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
The auto correlation of the input sequence.
The output can return a 2D array of double-precision, floating-point numbers or a 2D array of complex double-precision, floating-point numbers.
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:
