(genetics) (mathematics) One of a set of left singular vectors of a genes x samples matrix that tabulates, e.g., the mRNA or gene expression of the genes across the samples, where the samples were assayed by using DNA microarrays. The corresponding right singular vector is the corresponding eigengene.
