Walsh Hadamard Inverse (Not in Base Package)

Performs the inverse of the real Walsh Hadamard transform. Details  

	X is an array of power of 2 length.
	Walsh Hadamard Inverse {X} returns the inverse Walsh Hadamard transform of X.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

Walsh Hadamard Inverse Details

If WH{X} denotes the Walsh Hadamard transform of X and WHI{X} denotes the inverse Walsh Hadamard transform, then it is

WHI{WH{X}} = WH{WHI{X}} = X.

Furthermore, the following equation is valid

,

where n is the length of the signal X.
