container : Array, predefined Array for holding results

The GenerateJaehne(n, mag) command generates an n-dimensional Jaehne array. The result is returned in an Array with datatype float[8].

The Jaehne array of length $n$ is defined by computing the $k$-th sample as $m\sin \left(\frac{\mathrm{\pi }{k}^2}{2n}\right)$, where $m$ is the magnitude of the signal.

If the container=C option is provided, then the results are put into C and C is returned. With this option, no additional memory is allocated to store the result. The container must be an Array of size n having datatype float[8].

The SignalProcessing[GenerateJaehne] command is thread-safe as of Maple 17.

For more information on thread safety, see index/threadsafe.
