Matlab length of a vector

The explanation of this problem is a bit confusing. It can mean, that one should compute the length of the array itself or the length of a matlab length of a vector in a coordinate system. I saw what was meant looking at the tests. But before I was confused.

Help Center Help Center. For example, if A is a 3-by-4 matrix, then size A returns the vector [3 4]. If A is a table or timetable, then size A returns a two-element row vector consisting of the number of rows and the number of table variables. You can also specify dim as a vector of positive integers to query multiple dimension lengths at a time. For example, size A,[2 3] returns the lengths of the second and third dimensions of A in the 1-by-2 row vector szdim. You can query multiple dimension lengths at a time by specifying a vector dimension argument.

Help Center Help Center. 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. Find the length of a uniformly spaced vector in the interval [5,10]. Create a string array and compute its length, which is the number of elements in each row. Create a structure with fields for Day and Month.

For arrays with more dimensions, the length is max size X. Very fun problem. MathWorks Answers Support. Answers Support MathWorks. Input Arguments collapse all A — Input array scalar vector matrix multidimensional array.

Understanding the size and the number of elements within a vector is fundamental for effective data analysis and manipulation in MATLAB. In this article, we will explore various methods to achieve this goal using the size , length , and numel functions.

Then following the requirement's description. When dim is not specified and fewer than ndims A output arguments are listed, then all remaining dimension lengths are collapsed into the last argument in the list.
