Linked Representation In linked representations, you’ll use a linked list data structure to represent a sparse matrix. You will use two different nodes, the header node and the element node, in this linked list. The header node is made up of 3 fields while the is made up of 5 fields ...
2 Dimensional representation of sparse matrix by a 2D array leads to wastage of memory. Also, a number of zeros present in any of the sparse matrix with a blend of a number of non-zeros are somehow consumed time which gets reduced on the usage of a sparse matrix with respect to both c...

ExtendableSparseMatrix is aimed to work as a drop-in replacement to SparseMatrixCSC in finite element and finite volume codes especially in those cases where the sparsity structure is hard to detect a priori and where working with an intermediadte COO representation appears to be not convenient....
