Dense and Sparse MatricesВ¶ This chapter describes the two CVXOPT matrix types: matrix objects, used for dense matrix computations, and spmatrix objects, used for python code examples for scipy.sparse.csgraph.csgraph_to_dense. Learn how to use python api scipy.sparse.csgraph.csgraph_to_dense

9An index can be dense or sparse Вѕin our previous dense index example, we needed 1954 blocks for the index (#records / # index fields per block) There are two more famous types of primary index. Dense primary index. Sparse primary For example, one sparse index can point to more than one records of the main
