At each point where a function is differentiable , its Jacobian matrix can also be thought of as describing the amount of "stretching", "rotation" or "transforming" that the function imposes locally near that point. For example , if ( (x', y') = f(x,y) is used to smoothly transform...

Physically, the meaning of the 1D Jacobian matrix [dxdξ] can be described as the ratio of the x-coordinate to ξ-coordinate. For the previously described 1D bar element with x1 = 0 and x2 = L and Eq. (3.49) where x=12[(x1+x2)+(x2−x1)ξ], the Jacobian matrix is calculated...
Jacobian matrix is the basis of the kinematic performance index. However, the conventional Jacobian matrix is not usually dimensionally homogeneous due to the inhomogeneous physical units, caused by the different mathematical representations of the rotation and translation. In this paper, we propose a ...
