Method Details

add

public static CooTensor add(CooTensor src1,
 CooTensor src2)

Sums two sparse COO tensors and stores result in a new COO tensor.

Parameters:

src1 - First tensor in the sum.

src2 - Second tensor in the sum.

Returns:

The element-wise tensor sum of src1 and src2.

Throws:

LinearAlgebraException - If the tensors src1 and src2 do not have the same shape.

sub

public static CooTensor sub(CooTensor src1,
 CooTensor src2)

Computes difference between two sparse COO tensors and stores result in a new COO tensor.

Parameters:

src1 - First tensor in the difference.

src2 - Second tensor in the difference.

Returns:

The element-wise tensor difference of src1 and src2.

Throws:

LinearAlgebraException - If the tensors src1 and src2 do not have the same shape.

elemMult

public static CooTensor elemMult(CooTensor src1,
 CooTensor src2)

Computes the element-wise multiplication between two sparse COO tensors.

Assumes indices of both tensors are sorted lexicographically.

Parameters:

src1 - First tensor in the element-wise multiplication.

src2 - Second tensor in the element-wise multiplication.

Returns:

The element-wise product of src1 and src2.
