Contents: Description, Arguments, Usage, Examples, Images, Source Supported Under Version: > 1.00 Current .dvrc Version: 1.00 Description "Invert Independently About Zero" - inverts values while preserving their original sign Arguments and Return Values Arguments: An array of values Return Value: An array of the same size as the input Usage Syntax: iiaz(inputdata) This function, for each value in an array, inverts the distance between zero and the original maximum positive and negative values in the array. It preserves the sign of the original values, so positive values remain positive and negative values remain negative, with only their scale being inverted.
