up-sample a signal
UpSample( A, factor, phase )
Array of real or complex numeric values; the signal
posint, up-sample factor
nonnegint, (optional) phase
container : Array, predefined Array for holding results
The UpSample( A, factor, phase ) command up-samples the signal in the Array A.
The effect of this command is to place factor - 1 zeroes between each pair of samples in the Array A.
Before the code performing the computation runs, Maple converts A to a hardware datatype, first attempting float and subsequently complex, unless it already has one of these datatypes. For this reason, it is most efficient if A has one of these datatypes beforehand.
The phase argument determines an offset, so that the sample value from A occurs phase positions offset in the output array. The value of phase must be non-negative and less than the value of factor.
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 * factor, where N is the number of elements of A, and it must have datatype float if A is real and complex if A is complex.
The SignalProcessing[UpSample] command is thread-safe as of Maple 17.

The SignalProcessing[UpSample] command was introduced in Maple 17.
