### A Simple Example

```C++
#include
#include

#include
#include
#include
#include

#include

int main(void)
{
int cuda_major = CUDA_VERSION / 1000;
int cuda_minor = (CUDA_VERSION % 1000) / 10;
int thrust_major = THRUST_MAJOR_VERSION;
int thrust_minor = THRUST_MINOR_VERSION;
int cusp_major = CUSP_MAJOR_VERSION;
int cusp_minor = CUSP_MINOR_VERSION;
std::cout << "CUDA v" << cuda_major << "." << cuda_minor << std::endl;
std::cout << "Thrust v" << thrust_major << "." << thrust_minor << std::endl;
std::cout << "Cusp v" << cusp_major << "." << cusp_minor << std::endl;

// create an empty sparse matrix structure (HYB format)
cusp::hyb_matrix A;

// load a matrix stored in Matrix-Market format
cusp::io::read_matrix_market_file(A, "./testing/data/laplacian/5pt_10x10.mtx");

// allocate storage for solution (x) and right hand side (b)
cusp::array1d x(A.num_rows, 0);
cusp::array1d b(A.num_rows, 1);

// solve the linear system A * x = b with the conjugate gradient method
cusp::krylov::cg(A, x, b);

return 0;
}
```

CUSP is a header-only library. To compile this example clone both CUSP and [Nvidia/cccl](https://github.com/NVIDIA/cccl):
```shell
[email protected]:cusplibrary/cusplibrary.git
cd cusplibrary
git clone [email protected]:NVIDIA/cccl.git
nvcc -Icccl/thrust -Icccl/libcudacxx/include -Icccl/cub -I. example.cu -o example
```
