AnalysisLibErrType InvDST (double inputArray[], int numberOfElements, double outputArray[]);

Purpose

Computes the one-dimensional inverse Discrete Sine Transform (DST) of the input signal inputArray. If y represents the input sequence of DST{x}, the one-dimensional inverse DST of y is defined as follows:

where y is inputArray, x is outputArray, and N is numberOfElements.

Parameters

Input
Name Type Description
inputArray double-precision array The input sequence.
numberOfElements integer The number of elements in inputArray.
Output
Name Type Description
outputArray double-precision array The inverse DST of inputArray.

Return Value

Name Type Description
status AnalysisLibErrType A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants.
