Detailed Description

Convert a sparse COO matrix into a sparse CSR matrix.

hipsparseXcoo2csr converts the COO array containing the row indices into a CSR array of row offsets, that point to the start of every row. It is assumed that the COO row index array is sorted.

Note

It can also be used, to convert a COO array containing the column indices into a CSC array of column offsets, that point to the start of every column. Then, it is assumed that the COO column index array is sorted, instead.

This function is non blocking and executed asynchronously with respect to the host. It may return before the actual computation has finished.
