• ### Decompose matrix into outer product of vectors Physics

2012-9-17 · Vector outer product ALWAYS produces a rank 1 matrix at least among 3 3 matrices..think about it there are 6 independent components in the constituent vectors but 9 components in the resulting matrix. So there is a well-defined interdependence of the matrix components. You cannot hope for any random matrix to be expressed as an outer product.
