There are seven available sparse matrix types:1. csc_matrix: Compressed Sparse Column format2. csr_matrix: Compressed Sparse Row format3.bsr_matrix:BlockSparse Row format4. lil_matrix: List of Lists format5. dok_matrix:Dictionaryof Keys format6. coo_matrix: COOrdinate format (aka IJV, triplet...
Figure 7 illustrates the ELLPACK representation of an example matrix with a maximum of three nonzeros per row. As in the DIA format, data and indices are stored in column-major order. When the maximum number of nonzeros per row does not substantially differ from the average, the ELL ...

mean vector of \(Y_{t}\) is independent of the time t, and for any times t and s, the covariance matrix \(Cov(Y_{t},Y_{s})\) depends only on \(t-s\).In addition we assume that the process has zero mean (since any systematic trend can be always removed from the data)....
matrix has the property that only nonzero elements are stored in the underlying data structure.• Sparse storage can be used to construct a Matrix, Vector, Array, or table. This page focuses on sparse rtables. For information on and examples of sparse tables, see indexfcn/sparse.•...

in the graph are n pointers from each quodel, each to 1 specific quodel that is the correct place to point but statistically we often wont know which so use a row of a sparse stochastic matrix instead (map of quodel to chance) as pointer. Pointers also can be at "does not halt" ...
