SignalProcessing[MinimumEvery] - compute the pairwise minimum of two arrays of samples

SignalProcessing[MaximumEvery] - compute the pairwise maximum of two arrays of samples

Calling Sequence

MinimumEvery(A, B)

MaximumEvery(A, B)

Parameters

A, B

-

Arrays of real numeric values; the signals

Description

• 

The MinimumEvery(A, B) command computes the minimum of each pair A[k] and B[k], storing the minimum value in the corresponding k-th element of an Array with datatype float[8], which is then returned.

• 

The MaximumEvery(A, B) command computes the maximum of each pair A[k] and B[k], storing the maximum value in the corresponding k-th element of an Array with datatype float[8], which is then returned.

• 

The Vectors A and B must have the same number of elements.

• 

Before the code performing the computation runs, A and B are converted to datatype float[8] if they do not have that datatype already. For this reason, it is most efficient if A and B have this datatype beforehand.

• 

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], where N is the size of A and B.

Thread Safety

• 

The SignalProcessing[MinimumEvery] and SignalProcessing[MaximumEvery] commands are thread-safe as of Maple 17.

• 

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