◆ AddMM()

void open3d::core::AddMM ( const Tensor A,

Tensor C,
double  alpha,
double  beta 
)

Computes matrix multiplication C = alpha * A @ B + beta * C. If matrix A is a (n x m) tensor, and B is a (m x p) tensor, C should have a shape (n x p). alpha and beta are scaling factors on matrix-matrix multiplication and the added matrix input respectively.

◆ Append()

Tensor open3d::core::Append ( const Tensor self,

const utility::optional< int64_t > &  axis = utility::nullopt 
)

Appends the two tensors, along the given axis into a new tensor. Both the tensors must have same data-type, device, and number of dimensions. All dimensions must be the same, except the dimension along the axis the tensors are to be appended.

This is the same as NumPy's semantics:

Example:

Tensor a = Tensor::Init<int64_t>({{0, 1}, {2, 3}});
Tensor b = Tensor::Init<int64_t>({{4, 5}});
Tensor t1 = core::Append(a, b, 0);
// t1:
// [[0 1],
// [2 3],
// [4 5]]
// Tensor[shape={3, 2}, stride={2, 1}, Int64, CPU:0, 0x55555abc6b00]
Tensor t2 = core::Append(a, b);
// t2:
// [0 1 2 3 4 5]
// Tensor[shape={6}, stride={1}, Int64, CPU:0, 0x55555abc6b70]
Tensor Append(const Tensor &self, const Tensor &other, const utility::optional< int64_t > &axis)
Appends the two tensors, along the given axis into a new tensor. Both the tensors must have same data...
Definition: TensorFunction.cpp:118
Parameters
selfValues are appended to a copy of this tensor.
otherValues of this tensor is appended to the self.
axis[optional] The axis along which values are appended. If axis is not given, both tensors are flattened before use.
Returns
A copy of tensor with values appended to axis. Note that append does not occur in-place: a new array is allocated and filled. If axis is None, out is a flattened tensor.

◆ AtomicFetchAddRelaxed() [1/2]

uint32_t open3d::core::AtomicFetchAddRelaxed ( uint32_t *  address,
uint32_t  val 
)
inline

Adds val to the value stored at address and returns the previous stored value as an atomic operation. This function does not impose any ordering on concurrent memory accesses.

Warning
This function will treat all values as signed integers on Windows!

◆ AtomicFetchAddRelaxed() [2/2]

uint64_t open3d::core::AtomicFetchAddRelaxed ( uint64_t *  address,
uint64_t  val 
)
inline

Adds val to the value stored at address and returns the previous stored value as an atomic operation. This function does not impose any ordering on concurrent memory accesses.

Warning
This function will treat all values as signed integers on Windows!

◆ Concatenate()

Tensor open3d::core::Concatenate ( const std::vector< Tensor > &  tensors,
const utility::optional< int64_t > &  axis = 0 
)

Concatenates the list of tensors in their order, along the given axis into a new tensor. All the tensors must have same data-type, device, and number of dimensions. All dimensions must be the same, except the dimension along the axis the tensors are to be concatenated. Using Concatenate for a single tensor, the tensor is split along its first dimension (length), and concatenated along the axis.

This is the same as NumPy's semantics:

Example:

Tensor a = Tensor::Init<int64_t>({{0, 1}, {2, 3}});
Tensor b = Tensor::Init<int64_t>({{4, 5}});
Tensor c = Tensor::Init<int64_t>({{6, 7}});
Tensor output = core::Concatenate({a, b, c}, 0);
// output:
// [[0 1],
// [2 3],
// [4 5],
// [6 7]]
// Tensor[shape={4, 2}, stride={2, 1}, Int64, CPU:0, 0x55555abc6b00]
a = core::Tensor::Init<float>(
{{{0, 1}, {2, 3}}, {{4, 5}, {6, 7}}, {{8, 9}, {10, 11}}}, device);
output = core::Concatenate({a}, 1);
// output:
// [[0, 1, 4, 5, 8, 9],
// [2, 3, 6, 7, 10, 11]]
// Tensor[shape={2, 6}, stride={6, 1}, Int64, CPU:0, 0x55555abc6b00]
Tensor Concatenate(const std::vector< Tensor > &tensors, const utility::optional< int64_t > &axis)
Concatenates the list of tensors in their order, along the given axis into a new tensor....
Definition: TensorFunction.cpp:79
Parameters
tensorsVector of tensors to be concatenated. If only one tensor is present, the tensor is split along its first dimension (length), and concatenated along the axis.
axis[optional] The axis along which values are concatenated. [Default axis is 0].
Returns
A new tensor with the values of list of tensors concatenated in order, along the given axis.

Run a function in parallel on CPU or CUDA.

Parameters
deviceThe device for the parallel for loop to run on.
nThe number of workloads.
funcThe function to be executed in parallel. The function should take an int64_t workload index and returns void, i.e., void func(int64_t).
Note
This is optimized for uniform work items, i.e. where each call to func takes the same time.

Run a potentially vectorized function in parallel on CPU or CUDA.

Parameters
deviceThe device for the parallel for loop to run on.
nThe number of workloads.
funcThe function to be executed in parallel. The function should take an int64_t workload index and returns void, i.e., void func(int64_t).
vec_funcThe vectorized function to be executed in parallel. The function should be provided using the OPEN3D_VECTORIZED macro, e.g., OPEN3D_VECTORIZED(MyISPCKernel, some_used_variable).
Note
This is optimized for uniform work items, i.e. where each call to func takes the same time.
If you use a lambda function, capture only the required variables instead of all to prevent accidental race conditions. If you want the kernel to be used on both CPU and CUDA, capture the variables by value.
