Method Details

argMin

public static int argMin(double[] entries)

Computes the index of the minimum value in this tensor. If the minimum value occurs at more than one index, the index of the first occurrence is taken.

Parameters:

entries - Entries of the tensor.

Returns:

The index of the minimum value in this tensor. If there are zero entries in the array, -1 is returned.

argMax

public static int argMax(double[] entries)

Computes the index of the maximum value in this tensor. If the maximum value occurs at more than one index, the index of the first occurrence is taken.

Parameters:

entries - Entries of the tensor.

Returns:

The index of the maximum value in this tensor. If there are zero entries in the array, -1 is returned.

argEq

public static int argEq(double[] entries,
 double value)

Computes the index of the first entry in a tensor which is equal to the specified value.

Parameters:

entries - Entries of this tensor.

value - Value to find index of.

Returns:

The index of the first entry in entries which is equal to value. If no such value exists, then -1 is returned.

argEq

public static int argEq(int[] entries,
 int value)

Computes the index of the first entry in a tensor which is equal to the specified value.

Parameters:

entries - Entries of this tensor.

value - Value to find index of.

Returns:

The index of the first entry in entries which is equal to value. If no such value exists, then -1 is returned.
