    • innerProd

      public static org.ejml.data.Complex_F32 innerProd​(org.ejml.data.CMatrixRMaj x, org.ejml.data.CMatrixRMaj y, @Nullable @Nullable org.ejml.data.Complex_F32 output)

      Computes the inner product of the two vectors. In geometry this is known as the dot product.

      ∑k=1:n xk * yk
      where x and y are vectors with n elements.

      These functions are often used inside of highly optimized code and therefor sanity checks are kept to a minimum. It is not recommended that any of these functions be used directly.

      Parameters:
      x - A vector with n elements. Not modified.
      y - A vector with n elements. Not modified.
      Returns:
      The inner product of the two vectors.

    • innerProdH

      public static org.ejml.data.Complex_F32 innerProdH​(org.ejml.data.CMatrixRMaj x, org.ejml.data.CMatrixRMaj y, @Nullable @Nullable org.ejml.data.Complex_F32 output)

      Computes the inner product between a vector and the conjugate of another one.

      ∑k=1:n xk * conj(yk)
      where x and y are vectors with n elements.

      These functions are often used inside of highly optimized code and therefor sanity checks are kept to a minimum. It is not recommended that any of these functions be used directly.

      Parameters:
      x - A vector with n elements. Not modified.
      y - A vector with n elements. Not modified.
      Returns:
      The inner product of the two vectors.

    • outerProd

      public static void outerProd​(org.ejml.data.CMatrixRMaj x, org.ejml.data.CMatrixRMaj y, org.ejml.data.CMatrixRMaj A)

      Sets A ∈ ℜ m × n equal to an outer product multiplication of the two vectors. This is also known as a rank-1 operation.

      A = x * yT where x ∈ ℜ m and y ∈ ℜ n are vectors.

      Which is equivalent to: Aij = xi*yj

      Parameters:
      x - A vector with m elements. Not modified.
      y - A vector with n elements. Not modified.
      A - A Matrix with m by n elements. Modified.

    • outerProdH

      public static void outerProdH​(org.ejml.data.CMatrixRMaj x, org.ejml.data.CMatrixRMaj y, org.ejml.data.CMatrixRMaj A)

      Sets A ∈ ℜ m × n equal to an outer product multiplication of the two vectors. This is also known as a rank-1 operation.

      A = x * yH where x ∈ ℜ m and y ∈ ℜ n are vectors.

      Which is equivalent to: Aij = xi*yj

      Parameters:
      x - A vector with m elements. Not modified.
      y - A vector with n elements. Not modified.
      A - A Matrix with m by n elements. Modified.
