Detailed Description

Read-only view of a sparse matrix in compressed-row storage

format. Neither array elements (nonzeros) nor sparsity

structure can be modified. If modifications are required,

create a new view.

Index values begin at 0.

Storage requirements: An (m x n) matrix with

nz nonzeros requires no more than ((T+2I)*nz)

bytes, where T is the size of data elements and

I is the size of integer subscripts.
