L = length(X) returns the length of the largest array dimension in X. For vectors, the length is simply the number of elements. For arrays with more dimensions, the length is max(size(X)). The length of an empty array is zero.

23 Αυγ 2024 · I am looking for the magnitude of the vector r. It should be equal to r = (x^2 + y^2 + z^2)^0.5. on 3 Jun 2015. https://www.mathworks.com/matlabcentral/answers/86434-magnitude-of-a-vector#comment_289762. use the function norm (r) or mag=sqrt (sum (r.*r)) on 30 Jun 2019.
sz = size(A) returns a row vector whose elements are the lengths of the corresponding dimensions of A. For example, if A is a 3-by-4 matrix, then size(A) returns the vector [3 4].
12 Φεβ 2024 · The length() function in MATLAB is a simple yet powerful tool designed to provide the number of elements along the longest dimension of a vector or array. When applied to a vector, it directly returns the number of elements present in that vector.
Length of vector. Syntax. n = length (X) Description. The statement length (X) is equivalent to max (size (X)) for nonempty arrays and 0 for empty arrays. n = length (X) returns the size of the longest dimension of X. If X is a vector, this is the same as its length. Examples.
14 Ιουλ 2016 · numel will return the number of elements whether it is a row vector, column vector, or multi-dimensional array. We can easily test the performance of these by writing a quick benchmark. We will take the size with the various methods N times (for this I used 10000).
