Method Details

scalMult

public static <T extends Semiring<T>> void scalMult(T[] src,
 T factor,
 T[] dest)

Computes the scalar multiplication of a tensor.

Parameters:

src - Entries of the tensor.

factor - Scalar value to multiply.

dest - Array to store result in.

Throws:

ArrayIndexOutOfBoundsException - If dest is not at least the size of src.

scalMult

public static <T extends Semiring<T>> void scalMult(T[] src,
 T factor,
 T[] dest,
 int start,
 int stop)

Computes the scalar multiplication of a tensor.

Parameters:

src - Entries of the tensor.

factor - Scalar value to multiply.

dest - Array to store result in.

start - Starting index of scalar multiplication.

stop - Stopping index of scalar multiplication.

Throws:

ArrayIndexOutOfBoundsException - If dest is not the size of src.

add

public static <T extends Semiring<T>> void add(T[] src,
 T summand,
 T[] dest)

Sums a value to each entry of tensor.

Parameters:

src - Entries of the tensor (non-zero data if tensor is sparse).

summand - Value to sum to each entry of the tensor.

dest - Array to store result in.
