Hi Ludovic,

in the latest daily build, Wayne has added an Array.fourier(theArray,
windowType) macro function, based on code snippets that I have sent to
him. Use Help>Update ImageJ to obtain the daily build.

There is some documentation and a text macro for the new function at

http://imagej.nih.gov/ij/macros/examples/TestArrayFourier.txt

In your case, with data values approaching (or equel to) zero at the
beginning and end of the array, you don't need a window function; simply
omit that parameter or write "none" (with the quotes!) for the windowType.

Michael
