Sparse matrix multiplication is implemented as linear expanded DSP code automatically generated by specially designed program. The method is applied to predictive vector quantization of Line Spectrum Frequencies vectors used in speech coding. It will be shown that the obtained reduction in computational ...
Sparse Matrix C++ implementation of sparse matrix using CRS format. Usage Creation SparseMatrix comes as a template class, so we have to specify the element type. SparseMatrix::SparseMatrix<int> matrix(3); // 3×3 matrix of integers SparseMatrix::SparseMatrix<int> matrix2(4, 5); // 4×...
This paper presents a floating-point Sparse Matrix Vector Multiply(SMVM) on reconfigurable computing platform,because traditional implementation SpMXV on General Purpose Processor(GPP)is very inefficient.The design of SpMXV co-processor is based on IEEE-754 32 bit floating point data formats,diagonal...
Sparse matricesCurrent densityDensity measurementIn this paper, a novel matrix-thinning technique, matrix sparse decomposition (MSD) [Liu et al., 1998, 1999], has been implemented to solve the scattering of waves by two-dimensional (2-D) homogeneous dielectric cylinders for the first time. The ...
The matrix computation language and environment MATLAB is extended to include sparse matrix storage and operations. The only change to the outward appearance of the MATLAB language is a pair of commands to create full or sparse matrices. Nearly all the operations of MATLAB now apply equally to fu...
