### Python API Example
|
|
```python
|
|
import rtx_bindings as rtx
|
|
|
|
# PyTorch-compatible tensor creation
|
|
x = rtx.ones([2, 3], requires_grad=True)
|
|
y = rtx.ones([2, 3])
|
|
|
|
# Natural operations with autograd
|
|
z = x * y + x @ y.T
|
|
loss = z.sum()
|
|
|
|
# Gradient computation
|
|
loss.backward()
|
|
print(x.grad) # Computed gradients
|
|
|
|
# Device movement
|
|
gpu_tensor = x.cuda()
|
|
cpu_tensor = gpu_tensor.cpu()
|
|
|
|
# NumPy interop
|
|
np_array = x.numpy()
|
|
tensor_from_np = rtx.from_numpy(np_array)
|
|
```
|
|
|
|
### C API Example
|
|
```c
|
|
// Type-safe tensor operations
|
|
RTXTensor* tensor = NULL;
|
|
size_t shape[] = {2, 3};
|
|
|
|
RTXError result = rtx_zeros(shape, 2, "cpu", &tensor);
|
|
if (result == RTXError::Success) {
|
|
// Use tensor...
|
|
rtx_tensor_free(tensor);
|
|
}
|
|
```
