    • innerProduct

      public static <T extends Field<T>> T innerProduct(T[] src1, T[] src2)
      Computes the vector inner product for two vectors.
      Parameters:
      src1 - Entries of the first vector.

      Returns:
      The inner product of the two vectors.

    • innerSelfProduct

      public static double innerSelfProduct(Complex128[] src1)
      Computes the inner product (dot product) of a vector with itself.
      Parameters:
      vector - The input complex vector.
      Returns:
      The inner product of the vector with itself as a double.

    • dotProduct

      public static <T extends Field<T>> T dotProduct(T[] src1, T[] src2)
      Computes the vector dot product for two vectors.
      Parameters:
