The company behind hits like “The Matrix” and “Ocean’s Eleven” has filed for bankruptcy, the latest domino to fall in a struggling Hollywood industry. Village Roadshow Entertainment of West Hollywood, ...
I think the purpose of this was to communicate some symmetry of the problem to petsc, so it doesn't spend time trying to work it out itself. We should update how this is done, which might be an ...
The constrained least-squares n × n-matrix problem where the feasibility set is the subspace of the Toeplitz matrices is analyzed. The general, the upper and lower triangular cases are solved by ...

In this paper, we explore the inverse spectral problem for a kind of pseudo-symmetric matrix A(ε,c,s) that corresponds to a graph of a banana tree when all ε=1. The problem of reconstructing ...
