C. K. Jensen With the notation xreg = vec (Xreg ), (5) immediately leads to the expression n2 Xreg = φk k=1 uTk b [k] V , σk (6) where φk are the filter factors, σk are the singular values of A, uk are the left singular vectors, and V [k] are n × n matrices such that vk = vec V [k] are the right singular vectors. This relation shows that we can express the regularized solution Xreg as a weighted sum over the basis images V [k] . With the Kronecker-product form of the PSF matrix A, Eq. (4) shows that there are simple expressions for the singular values and vectors.

If the straight right-looking formulation is regarded as one with the look-ahead of zero, then the left-looking formulation is equivalent to the right looking formulation with the maximum possible look-ahead for a given problem. Applying the idea of dynamic execution flow definition to LU factorization leads to the implementation of the left-looking variant of the algorithm, where the panel factorizations are performed as soon as possible, with the modification that if the panel factorization introduces a stall, then an update to a block of columns (or rows) of the right submatrix is performed instead.
