in Cartesian coordinates. The direction of is the orientation in which the directional derivative has the largest value and is the value of that directional derivative. Furthermore, if , then the gradient is perpendicular to the level curve through if and perpendicular to the level surface throug...
Those four numbers, are the components of the "metric tensor" in the coordinate system. In cartesian coordinates , it's trivial: . But in polar coordinates, it's a little more interesting: . The metric tensor is how you compute dot-products of two vectors: . For cartesian coordinates...
gradient(f,v) finds the gradient vector of the scalar function f with respect to vector v in Cartesian coordinates. If you do not specify v, then gradient(f) finds the gradient vector of the scalar function f with respect to a vector constructed from all symbolic variables found in f. Th...
In this paper, we propose an inverse method for full gravity gradient tensor data in the spherical coordinate system. As opposed to the traditional gravity inversion in the Cartesian coordinate system, our proposed method takes the curvature of the Earth, the Moon, or other planets into account,...

Here's my answer: distance is distance. 13 units is 13 units. But in some situations we are "measuring our coordinates" (what are the values of x & y) andnotthe distance itself. Cartesian coordinates (x-axis, y-axis) are very inefficient for diagonal motion (i.e., you are measuring...
The in-house direct numerical simulation (DNS) code solves the incompressible Navier-Stokes equation for pressure and velocity fields in Cartesian coordinates with the flow directions as streamwise (x), wall-normal (y) and spanwise (z). In this paper, the mean velocity components are denoted by...
In Cartesian coordinates x,y,z, the gradient Richardson number Ri is the ratio between the square of the buoyancy frequency N and the square of the vertical shear S, Ri=N2/S2, where N2=g/ρρ/z and S2=u/z2+v/z2, with ρ potential density, u,v the horizontal velocity components ...
