I recall that there was a discussion about whether we should just drop the FFT code (IIRC due to its being much less efficient than alternatives).

Rob Tompkins commented on MATH-1385:
The issue at hand here is that we have no upper limits on the size of the array
returned by {{TransformUtils.createComplexArray}}, and this causes the
potential for memory profile limitations.
I wonder if we could somehow perform the transform in portions as opposed to
doing a complete copy of the input data here:
https://github.com/apache/commons-math/blob/MATH_3_6_1/src/main/java/org/apache/commons/math3/transform/FastFourierTransformer.java#L370-L372
or minimally not make a second copy of the data in the {{TransformUtils}}.
