Advanced Analysis Library Only
AnalysisLibErrType InvDCT (double inputArray[], ssize_t numberOfElements, double outputArray[]);
Purpose
Computes the one-dimensional inverse Discrete Cosine Transform (DCT) of the input sequence. If inputArray represents the input sequence of DCT{x}, the one-dimensional inverse DCT of inputArray is defined as follows:
where
y denotes inputArray, x denotes outputArray, and N denotes numberOfElements.
Parameters
| Input | ||
| Name | Type | Description |
| inputArray | double [] | The input sequence. |
| numberOfElements | ssize_t | The number of elements in inputArray. |
| Output | ||
| Name | Type | Description |
| outputArray | double [] | The inverse DCT 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. |
