[Bug-gsl] Documentation errors

[Torquil Macdonald Sørensen]

Hello,

I have found two errors in the GSL documentation (both online and in my 
debian unstable GSL documentation), in the Fast Fourier Transforms section:

1) In the section "Overview of real data FFTs", in the formula for c_k, 
the subscript on x should be j, not k, since the sum is over j.

2) In the section "Radix-2 FFT routines for real data", under the 
description of the "gsl_fft_real_radix2_transform"-function. In the 
table showing the arrangement of the output data,
"complex[N/2].real = 0" should be "complex[N/2].imag = 0", shouldn't it?

Best regards,
Torquil Sørensen
