In the documentation, it is stated that for FFT, the array size can be at max 2^14.

This is confirmed in the following line:

framework/Sources/Accord.Math/AForge.Math/FourierTransform.cs

Line 312 in a5a2ea8

private const int maxLength = 16384;

Why is it so? There are other libraries (for example, Matnet.Numerics) that allow for a larger sample size.

Is there something that can be made about it?
