Detailed Description

template<typename Index>
class COO< Index >

A COO matrix backed by CUDA Unified Memory, with a CSR rowPtr.

Copying to a GPU kernel by value will cause the underling memory to be copied as well. For read-only GPU access, use the view() method to get a lightweight reference to the data.
