So I didn't test for the for loop and Divkar's bsxfun, but you can see that for arrays smaller than 3e4 kron is better than bsxfun, and this changes at larger arrays (ratio of <1 means kron took less time given the size of the array). And here it is: range=3*round(logspace(1,6,200)) So I tried to check using timeit my two solutions (because they are one liners it's easy). Ok, this got me curios, as I know bsxfun starts to be less efficient for bigger array sizes. Here's a bsxfun solution (less elegant, but hopefully faster): 3 1])),3,)' The simplest method is to use the backslash operator: xlsAy. Your precious feedbacks are very important to us.A slightly shorter and vectorized way will be (if a is your matrix) : b=a-kron(a(1:3:end,:),ones(3,1)) There are several ways to compute xls in Matlab. This article is prepared for completely educative and informative purposes. Leave your comments and questions below about the ‘norm()’ command in Matlab®! The use of the norm() command to calculate Euclidean norms of vectors in Matlab® is very simple like above. YOU CAN LEARN MatLab® IN MECHANICAL BASE Click And Start To Learn MatLab®!Īlso, you can do mathematical calculations with the norm() function as shown above in Matlab®. This is the general rule of Euclidean norm. The calculation is done with this calculation the root of 4^2+1^2+5^2. We calculated the Euclidean norm of this vector with the norm() command by simply type the variable ‘a’ inside the norm(). How To Use The ‘norm()’ Command In Matlab®? > a = įor example, we created a vector that has three elements called ‘a’ as shown above in Matlab®. In this article, we will show you how to index the Euclidean norms of vectors with the ‘norm()’ command in Matlab® with a very basic example below. In Matlab®, you can calculate and index the Euclidean norms of vectors. In some vector mechanics calculations or various kinds of mathematical calculations, the norms of vectors could be required.
