A representation of a sparse matrix is generated that includes a value array, a column array, a pointer array, and a row array. The value array includes the nonzero elements of the sparse matrix. The column array includes a column number where a value is located in the sparse matrix. ...
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 ...
Sparse matrix class The sparse matrix classsparsecan be initialised in several ways including from anRcpp::NumericMatrixand anEigen::MatrixXd. It is effectively a container for a sparse matrix representation of the matrix. It can also just be initialised by specifying the rows and columns and la...
Given any signalx∈Rnx∈Rn, we can obtain sparse representationθ∈Rnθ∈Rnofxxin two ways: Basis expansion: given sparse-inducing othonormal basis matrixB∈Rn×nB∈Rn×n, e.g., discrete cosine transform (DCT) matrix, iscrete wavelet transform (DWT) matrix, free-types filter banks of DWT...

Direction-of-Arrival Estimation of Wideband Signals via Covariance Matrix Sparse Representation This paper focuses on direction-of-arrival (DOA) estimation of wideband signals, and a method named wideband covariance matrix sparse representation (W-CMS......

Sparsity in networks corresponds to the situation where the actual number of edges in the network is much smaller than the maximum number of edges that is theoretically possible. Since actual networks that are large also tend to be sparse20,21,22, obtaining a sparse representation of the network...
Sparse matrix-vector multiplication (SpMV) is a fundamental computational kernel used in scientific and engineering applications. The nonzero elements of sparse matrices are represented in different formats, and a single sparse matrix representation is not suitable for all sparse matrices with different ...
