Scale 2D (Not in Base Package)

Determines scale and offset and then scales the input matrix, X, using these values. Details

X is the 2D input array.
Y=(X-offset)/scale is the output array.
scale is the scaling factor.
offset is the offset factor.
error returns any error or warning condition from the VI.

Scale 2D Details

The 2D output array

Y = (X - offset)/scale

is given by

scale = 0.5(max - min)

and

offset = min + 0.5 scale

where max denotes the maximum value in X, and min denotes the minimum value in X. Each element of Y is given by

Y[i,j] = (X[i,j] – offset)/scale.

You can use this VI to normalize any numerical sequence with the assurance that the range of the output sequence is [–1:1].
