| N = vecnorm(A, p, dim) |
vector, matrix or multidimensional array
Norm type: 2 (default), a positive scalar, or Inf.
positive integer scalar
norm: scalar or vector
vecnorm computes the 2-norm or Euclidean norm of the input array A
If A is a vector, vecnorm returns the norm of the vector.
If A is a matrix, vecnorm returns the norm of each column.
For multidimensional arrays, vecnorm returns the norm along the first array dimension whose size does not equal 1.
To compute the generalized vector p-norm, you can use the syntax N = vecnorm(A, p).
To operate along a specific dimension dim, the function can be called as N = vecnorm(A, p, dim).
In this case, the size of the specified dimension reduces to 1, while the sizes of all other dimensions remain unchanged.
A = [1, 2, 3; 4, 5, 6; 7, 8, 9];
n = vecnorm(A)
n = vecnorm(A, 2, 2)
n = vecnorm(A, 1)
