Function cusparseCgebsr2gebsc 

pub unsafe extern "C" fn cusparseCgebsr2gebsc(
    handle: cusparseHandle_t,
    mb: c_int,
    nb: c_int,
    nnzb: c_int,
    bsrSortedVal: *const cuComplex,
    bsrSortedRowPtr: *const c_int,

This function can be seen as the same as csr2csc() when each block of size rowBlockDim*colBlockDim is regarded as a scalar.

This sparsity pattern of the result matrix can also be seen as the transpose of the original sparse matrix, but the memory layout of a block does not change.

The user must call gebsr2gebsc_bufferSize() to determine the size of the buffer required by gebsr2gebsc(), allocate the buffer, and pass the buffer pointer to gebsr2gebsc().

• The routine requires no extra storage if pBuffer != NULL
• The routine supports asynchronous execution if the Stream Ordered Memory Allocator is available
• The routine supports CUDA graph capture if the Stream Ordered Memory Allocator is available.
