function varargout=bss_decomp_gain(varargin)

> decompose an estimated source into target/interference/noise/artefacts components, assuming the admissible distortion is a pure time-invariant gain.
>
> Usage:
>
> [s_target,e_interf[,e_noise],e_artif]=bss_decomp_gain(se,index,S[,N])
>
> Input:
> - se: row vector of length T containing the estimated source,
> - index: points which component of S se has to be compared to,
> - S: n x T matrix containing the original sources,
> - N: m x T matrix containing the noise on the obseravtions (if any).
>
> Output:
> - s_target: row vector of length T containing the target source(s)
> contribution,
> - e_interf: row vector of length T containing the interferences
> contribution,
> - e_noise: row vector of length T containing the noise contribution (if
> any),
> - e_artif: row vector of length T containing the artifacts
> contribution.
