I am using the cusp library with CUDA to use sparse matrix. Can't I use it in a `struct`

in C like:

```
#include <cusp/coo_matrix.h>
#include <cusp/multiply.h>
#include <cusp/print.h>
#include <cusp/transpose.h>
struct Cat{
int id;
cusp::coo_matrix<int, double, cusp::host_memory> A(2,100,10);
};
int main(){
}
```

I am getting the errors:

```
try.cu(7): error: expected a type specifier
try.cu(7): error: expected a type specifier
try.cu(7): error: expected a type specifier
```

What is the correct way to use it in a `struct`

so that I can have array of such structures?

That piece of code `coo_matrix`

looks suspiciously like a C++ template. If so, provide your `Cat struct`

with constructor and initialize A there:

```
struct Cat {
int id;
cusp::coo_matrix<int, double, cusp::host_memory> A;
Cat(): id(0), A(2,100,10) {}
}
```
