how to find norm of each vector in one matric in Matlab?

1 次查看(过去 30 天)
Let's say:
Matrix A=[3 2 1 %vector 1
1 1 1] %vector 2
How to find norm of each vector of matrix A? I hope the result will same as follow:
output= [sqrt(14) <---- norm(vector1)= sqrt(14)
sqrt(3) ] <---- norm(vector2)= sqrt(3)
output= [ 3.74
1.73 ]
I know if we use the syntax "norm", so we can find the norm of each vector. But if I use: norm(A), the result is NOT same as my expectation

sqrt(sum(A.^2,2))

If you're using release R2017b or later, use vecnorm with both the norm (p) and dimension (dim) optional inputs.
