Method Details

elemDiv

public static double[] elemDiv(double[] src1,
 Shape shape1,
 double[] src2,
 Shape shape2)

Computes the element-wise division of two tensors.

Parameters:

shape1 - Shape of the first tensor.

src2 - Second tensor in element-wise division.

shape2 - Shape of the second tensor.

Returns:

The element-wise division of the two tensors.

Throws:

IllegalArgumentException - If the tensors do not have the same shape.

elemDivConcurrent

public static double[] elemDivConcurrent(double[] src1,
 Shape shape1,
 double[] src2,
 Shape shape2)

Computes the element-wise division of two tensors using a concurrent algorithm.

Parameters:

src1 - First tensor in element-wise division.

shape1 - Shape of the first tensor.

src2 - Second tensor in element-wise division.

shape2 - Shape of the second tensor.

Returns:

The element-wise division of the two tensors.

Throws:

IllegalArgumentException - If the tensors do not have the same shape.

dispatch

public static double[] dispatch(double[] src1,
 Shape shape1,
 double[] src2,
 Shape shape2)

Dynamically chooses and applies element-wise division algorithm to use based on the number of entries in the tensors.

Parameters:

src1 - Entries of first tensor.

shape1 - Shape of first tensor.

src2 - Entries of second tensor.

shape2 - Shape of second tensor.

Returns:

The element-wise division of the two tensors.
