Chapter 4: Sparse Matrices, Defined Operations, Overloaded Assignment
This executable puts the sparse matrix utilities and defined operations through tests. Each of the defined operations .p., .t., and defined + (for HB represented matrices) are tested by comparing with dense matrix operations.
There is a single executable file which the makefile will generate
- testSparseStruct uses set_precision.f90, sortElements.f90, sparseSort.f90, sparseTypes.f90, sparseAssign.f90, sparseOps.f90, sparseUtils.f90.
Sample output from testSparseStruct
Test Status Description 1 Passed set and getExpansion factor tests 2 Passed HB Matrix Agrees with Dense Equivalent Matrix. 3 Passed HB Matrix Accumulation test 4 Passed HB Matrix (.t.) Agrees with Dense Matrix Transpose. 5 Passed HB Matrix * Vector (.p.) Agrees with Dense Matrix * Vector 6 Passed Vector * HB Matrix (.p.) Agrees with Vector * Dense Matrix 7 Passed HB Matrix + HB Matrix Agrees with Dense Matrix Sum.
