Hi, Alan. 'require' is only for clojure libs. For Java packages, use 'import':
user=> (import '[edu.emory.mathcs.jtransforms.fft DoubleFFT_1D]) edu.emory.mathcs.jtransforms.fft.DoubleFFT_1D user=> (def da (double-array (range 0 10 0.01))) #'user/da user=> (def fft (DoubleFFT_1D. (count da))) #'user/fft user=> (.realForward fft da) ;; operates in-place Reflection warning, /tmp/form-init1030205091778006036.clj:1:9 - call to realForward can't be resolved. user=> (first da) 5004.999999999934 Also, as you may already be aware, the Maven coordinates and the Java package names are not necessarily the same or even similar. --Leif On Wednesday, April 30, 2014 11:40:31 AM UTC-4, Alan Forrester wrote: > > I would like to try the JTransforms Java FFT library from Clojure: > > https://sites.google.com/site/piotrwendykier/software/jtransforms > > I created a new folder went to that folder in a console and typed > > lein try net.sourceforge.jtransforms/jtransforms "2.4.0" > > lein try retrieved some jars and poms from central, presumably > jtransforms and its dependencies and started a REPL. > > Having got this far I can't seem to figure out how to require > jtransforms in the REPL.
