25-Feb-2019 10:04:20 plasma_matrix_test MATLAB version. Test plasma_matrix Create a large sparse plasma matrix and right hand side. Store the matrix and right hand side in a Harwell-Boeing file. Then retrieve the information. PLASMA_MATRIX_TEST01 Linear order of spatial grid = 5 Number of grid points is 25 Approximate number of nonzero matrix entries is 125. Full storage matrix would require 625 entries. Sparsity image saved as "plasma_5_sparsity.png" Norm of solution is 0.315693 Matrix and right hand side saved in Harwell-Boeing format file "plasma_5_rua.txt" After writing the linear system to a file, and retrieving it, the norm of the solution is 0.315693 PLASMA_MATRIX_TEST01 Linear order of spatial grid = 100 Number of grid points is 10000 Approximate number of nonzero matrix entries is 50000. Full storage matrix would require 100000000 entries. Sparsity image saved as "plasma_100_sparsity.png" Norm of solution is 29.5723 Matrix and right hand side saved in Harwell-Boeing format file "plasma_100_rua.txt" After writing the linear system to a file, and retrieving it, the norm of the solution is 29.5723 plasma_matrix_test Normal end of execution. 25-Feb-2019 10:05:02
