AForge.Math.FourierTransform.FFT unhandled exception #156

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Running an FFT on a data sample produces an exception.

What is the expected output? What do you see instead?

I should see the input frequency.

What version of the product are you using?

Latest.

Please provide any additional information below.

I've attached a simple test case.

I create a simple array of complex and attempt to get back the original 
frequency.

Unfortunately I get an exception.

Isolated example attached.

This may be a defect, but it is also as documented.

FourierTransform.FFT is documented to only accept arrays of length 2, 4, 8, 16, 
32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, or 16384. The passed array has 
22050 elements, and the exception documented to be throw in such a situation is 
indeed thrown.

If this behavior is documented, then I don't see a defect/bug really. I think 
it is a bug, when people expect something from software, which is not supposed 
to be done and it is documented that it is NOT done.

So, if all happens like it is said in docs, then maximum what this ticket may 
pretend is an Enhancement request, not Defect report.

Closing the ticket since it describes a bug, which does not exist. Current 
behavior corresponds to documentation.
