Method Details

sum

public static double sum(double[] entries)

Computes the sum of all entries in this tensor. This can be applied to either real dense or spase tensors.

Parameters:

entries - Entries of the tensor.

Returns:

The sum of all entries in this tensor.

min

public static double min(double[] entries)

Computes the minimum value in a tensor. Note, if the entries array is empty, this method will return 0 allowing this method to be used for real sparse or dense tensors.

Parameters:

entries - Entries of the tensor.

Returns:

The minimum value in the tensor.

max

public static double max(double[] entries)

Computes the maximum value in a tensor. Note, if the entries array is empty, this method will return 0 allowing this method to be used for real sparse or dense tensors.

Parameters:

entries - Entries of the tensor.

Returns:

The maximum value in the tensor.

minAbs

public static double minAbs(double[] entries)

Computes the minimum absolute value in a tensor. Note, if the entries array is empty, this method will return 0 allowing this method to be used for real sparse or dense tensors.

Parameters:

entries - Entries of the tensor.

Returns:

The minimum absolute value in the tensor.

maxAbs

public static double maxAbs(double... entries)

Computes the maximum absolute value in a tensor. Note, if the entries array is empty, this method will return 0 allowing this method to be used for real sparse or dense tensors.

Parameters:

entries - Entries of the tensor.

Returns:

The maximum absolute value in the tensor.
