Gradient Gradient The gradient is a vector operator denoted and sometimes also called Del or nabla. It is most often applied to a real function of three variables , and may be denoted (1) For general curvilinear coordinates, the gradient is given by (2) which simplifies to (3) in Cartesian coordinates. The direction of is the orientation in which the directional derivative has the largest value and is th.. 더보기 이전 1 ··· 563 564 565 566 567 568 569 ··· 610 다음
