Various embodiments relating to encoding a sparse matrix into a data structure format that may be efficiently processed via parallel processing of a computing system are provided. In one embodiment, a sparse matrix may be received. A set of designated rows of the sparse matrix may be traversed ...
If the sparse matrix has diagonals containing only zero elements, then the diagonal storage format can be used to reduce the amount of information needed to locate the non-zero elements. This storage format is particularly useful in many applications where the matrix arises from a finite element ...
Frame theory is a rather new approach in signal modeling in the context of sparse matrices, worthwhile introducing to the statistical community. The basic construct is that linear measurements of a signal are described as a product of a matrix and the signal, where the rows of the matrix ...

in block triangular form and the algorithms are used on the graph of each block on the diagonal. We also assume thatAhasno rows or columns that are (almost) dense. If it does, a simple strategy is to remove them before applying the ordering algorithm to the remaining matrix; the ...
For an M -by-N matrix with a maximum of K nonzeros per row, the ELLPACK format stores the nonzero values in a dense M -by-K array data, where rows with fewer than K nonzeros are zero-padded. Similarly, the corresponding column indices are stored in indices, again with zero, or...
mean vector of \(Y_{t}\) is independent of the time t, and for any times t and s, the covariance matrix \(Cov(Y_{t},Y_{s})\) depends only on \(t-s\).In addition we assume that the process has zero mean (since any systematic trend can be always removed from the data)....
