multiply an array of samples by a triangular windowing function
Array of real or complex numeric values; the signal
container : Array, predefined Array for holding results
inplace : truefalse, specifies that output should overwrite input
The TriangleWindow(A) command multiplies the Array A by the triangular windowing function and returns the result in an Array having the same length.
The triangular windowing function w⁡k is defined as follows for a sample with N points.
where m=N2 for even N, and m=N2−12 for odd N.
Before the code performing the computation runs, A is converted to datatype float or complex if it does not have one of those datatypes already. For this reason, it is most efficient if A has one of these datatypes beforehand. This does not apply if inplace is true.
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 the same size and datatype as A.
If the inplace or inplace=true option is provided, then A is overwritten with the results. In this case, the container option is ignored.
