The method involves reading a matrix of cells and location of reference stars and calculating estimated positions of the stars. Size of window surrounding the estimated positions is calculated according to a maximum passing speed. Additional stars are searched by reading bands of lines at each time...

001-3 变为 001 -3 所以两个基础解系为：(-1 1 0 0)、（-7 0 3 1)即为 null space的一组基
Y Nakatsukasa,T Soma,A Uschmajew 摘要: For a given matrix subspace, how can we find a basis that consists of low-rank matrices? This is a generalization of the sparse vector problem. It turns out that when the subspace is spanned by rank-1 matrices, the matrices can be obtained by ...

The article discusses a significant expansion of the basis of two-level quasi-orthogonal Hadamard-Mersenne matrices, used for compression and masking of images and video stream frames. The article presents the dependences of the levels of matrix elements on their order, and the algorithm for calcula...
