FFTW.jl error in `fwht_natural`

[khoogveld]

Dear all,

I am currently looking into the work of @matthiasbe on the Subsampled Randomized Hadamard Transform (SRHT) who developed a Julia package based on Hadamard.jl.

Find bellow a reproducer of the error I encounter:
F = fwht_natural(Matrix(I(1024)), 1)
The following error occurs:
MethodError: no method matching getindex(::typeof(FFTW.libfftw3))

I have seen in other issues problems related to the update of the FFTW.jl package. For that reason I decided to work with the master branch of Hadamard.jl. This did not solve my problem. Any insight on the error I face?

Thank you in advance for your help.
Best,
Karmijn

Thanks, looks like this was broken by JuliaMath/FFTW.jl#316 (the perils of using undocumented FFTW.jl internals) … I should have a fix shortly.
