I'm having a problem with java interop using one of the libraries in
the Incanter package.
When I run the following code:
(use '(incanter core charts))
(import (edu.emory.mathcs.jtransforms.fft FloatFFT_2D))
(def xt (make-array Double/TYPE 3 3 ))
(for [x (range 3) y (range 3)] (aset xt x y 1))
(.realForward (FloatFFT_2D. 3 3) xt)
I get this error:
java.lang.IllegalArgumentException: No matching method found:
realForward for class edu.emory.mathcs.jtransforms.fft.FloatFFT_2D
That code is calling this method:
http://incanter.org/docs/parallelcolt/api/edu/emory/mathcs/jtransforms/fft/FloatFFT_2D.html#realForward%28float[][]%29
But if I do the same thing but call this method instead which takes a 1d
array as an argument instead it works:
http://incanter.org/docs/parallelcolt/api/edu/emory/mathcs/jtransforms/fft/FloatFFT_2D.html#realForward%28float[]%29
I'm pretty new to Clojure so I'm not sure what's going on here, but I
guess this has something to do with reflection? Is this going to be a
general problem with passing multidimensional arrays to Java methods
from Clojure?
Thanks,
