The vector–matrix product uT ⋅ B: = fB(u) = rowsum ∘ hB(u). Since matrix multiplication A ⋅ B is a sequence of fB(ai) computations, one for each row of A, one can apply a mantissa-based integer row checksum test to the hB (ai) components to precisely check for errors ...

SGEMV and DGEMV compute the matrix-vector product for either a real general matrix or its transpose, using the scalars α and β, vectors x and y, and matrix A or its transpose: y← β y+α Ax y ← βy+α ATx CGEMV and ZGE...
Vector space over a field Before giving a definition of inner product, we need to remember a couple of important facts about vector spaces. When we use the term "vector" we often refer to an array of numbers, and when we say "vector space" we refer to a set of such arrays. However,...
‘). We can use the matrix transpose and multiplication operation to create a vector inner product in the following manner. Suppose w and v are m*1 vectors. Then the inner product ( also known as the dot product ) is given by w’*v. the inner product of two vectors is a 矩阵移置...
uT represents the transpose of the vector u. ‖u‖ represents the length (L2 norm) of the vector, meaning the root of the squared elements. ‖u‖=u12+u22...+un2 θ (theta) is the angle between the vectors. We use the dot (⋅) symbol to characterize this operation, hence its na...

If U is a subspace of an inner product space V, then the only vector common to both U and U┴ is the zero vector. ∎ If S is a spanning set for a subspace U of ℝn (considered as column matrices) and if a matrix A is created so that each row of A is the transpose of ...
