Ezfftf

A variable containing one or more periodic sequences to be transformed. For a multi-dimensional array the rightmost dimensionwill be transformed. The size of the rightmost dimension need not be a power of 2. Skatīt vairāk A double array is returned if xisdouble, otherwise a float array is returned. If npts is thesize of the dimension to be transformed, and N representsall other variable … Skatīt vairāk There's a bug in V6.1.2 and earlier of this functionin which if "npts" is odd, the wrong values are returned. This isfixed in V6.2.0. Given a real periodic sequence x, ezfftfperforms a forward Fourier transform. This is often called … Skatīt vairāk http://ruby.gfd-dennou.org/products/ruby-dcl/ruby-dcl-doc/math2/node8.html
