Method Details

sub

public static <T extends Ring<T>>
SparseVectorData<T> sub(Shape shape1,
 T[] src1,
 int[] src1Indices,
 Shape shape2,
 T[] src2,
 int[] src2Indices)

Computes the element-wise vector subtraction between two real sparse vectors. Both sparse vectors are assumed to have their indices sorted lexicographically.

Parameters:

src1 - First sparse vector in the difference. Indices assumed to be sorted lexicographically.

src2 - Second sparse vector in the difference. Indices assumed to be sorted lexicographically.

Returns:

A data class containing the non-zero data and indices of the sparse COO vector resulting from the vector subtraction.

Throws:

IllegalArgumentException - If the two vectors do not have the same size (full size including zeros).

inner

public static <T extends Ring<T>> T inner(AbstractCooRingVector<?,?,?,?,T> src1,
 AbstractCooRingVector<?,?,?,?,T> src2)

Computes the inner product of two complex sparse vectors. Both sparse vectors are assumed to have their indices sorted lexicographically.

Parameters:

src1 - First sparse vector in the inner product. Indices assumed to be sorted lexicographically.

src2 - Second sparse vector in the inner product. Indices assumed to be sorted lexicographically.

Returns:

The result of the vector inner product.

Throws:

IllegalArgumentException - If the two vectors do not have the same size (full size including zeros).
