Takes data list as input, and returns list of indices to be used for downsampling.
Utilizes step method returning every n-th index, where step is calculated as follows: step = len(data) / n_out.
- Parameters:
- data: IDSNumericArray
data to be down-sampled
- n_out: int
desired size of data after downsampling
- *args
