> Mathematical error in comment for FastCosineTransformer
> -------------------------------------------------------
>
> Key: MATH-205
> URL: https://issues.apache.org/jira/browse/MATH-205
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 1.2
> Reporter: Roman Werpachowski
> Priority: Trivial
>
> The formula in the comments for transform() method of FastCosineTransformer
> has the form:
> F_n = (1/2) [f_0 + (-1)^n f_N] + \Sum_{k=0}^{N-1} f_k \cos(\pi nk/N)
> This is incorrect and should be
> F_n = (1/2) [f_0 + (-1)^n f_N] + \Sum_{k=1}^{N-1} f_k \cos(\pi nk/N)
