Gradient row vector

WebA fancy name for a row vector is a “covector” or linear form, and the fancy version of the relationship between row and column vectors is the Riesz representation theorem, but until you get to non-Euclidean geometry you may be happier thinking of a row vector as the transpose of a column vector. Lecture 2 Lecture Notes WebThe gradient vector Suggested background The derivative matrix The matrix of partial derivatives of a scalar-valued function, f: R n → R (confused?), is a 1 × n row matrix: D f ( x) = [ ∂ f ∂ x 1 ( x) ∂ f ∂ x 2 ( x) ⋯ ∂ f ∂ x n ( x)].
