Explicitly operating on a sub array and assign it back is a good approach. However, may I propose a bit of refactoring according to Matt Fig above:編
This MATLAB function applies the element-wise binary operation specified by the function handle fun to arrays A and B.

The simplest case of CUDA®kernel creation is from MATLAB®functions that contain scalarized, element-wise math operations. When element-wise operations are enclosed within a for-loop body, concurrent CUDA threads can be invoked to compute each loop iteration in parallel. Because CUDA threads do...
elements of a vector space, and hence matrices are, and then indeed, a 3x1 matrix and a 1x3 matrix are *not* members of the same vector space -- even though the two vector spaces are isomorphic to each other) The matlab induced --> applied linear algebra / math ...

^是对单个数或者是n阶矩阵（大小n*n）求幂，如2^3=8 你的程序里面的 xs1 xs2是m*n的矩阵吧？对这种矩阵的元素求幂要用.^
quatC = A.*B returns the element-by-element quaternion multiplication of quaternion arrays. You can use quaternion multiplication to compose rotation operators: To compose a sequence of frame rotations, multiply the quaternions in the same order as the desired sequence of rotations. For example, ...
