ST_CM_ArgSort_InitPars

Function block-specific structure with initialization parameters, which are analyzed when the function block is initialized.

• nInLength is the length of the input array.
• bSortDownward is a flag with which you can select whether the data are to be sorted in ascending or descending order. If bSortDownward is TRUE, then the largest values are placed at the front.
• fScaleFactor can be used in order to directly display, for example, the amplitude with associated frequencies instead of the index position (fScaleFactor = 1).
• nChannels defines the number of independent channels. This must be greater than zero.
