Singular value

Visualisation of a singular value decomposition (SVD) of a 2-dimensional, real shearing matrix M. First, we see the unit disc in blue together with the two canonical unit vectors. We then see the action of M, which distorts the disc to an ellipse. The SVD decomposes M into three simple transformations: a rotation V*, a scaling Σ along the rotated coordinate axes and a second rotation U. Σ is a diagonal matrix containing in its diagonal the singular values of M, which represent the lengths σ1 and σ2 of the semi-axes of the ellipse.

In mathematics, in particular functional analysis, the singular values, or s-numbers of a compact operator T: XY acting between Hilbert spaces X and Y, are the square roots of the eigenvalues of the non-negative self-adjoint operator T*T: XX (where T* denotes the adjoint of T).
