Matlab length of a vector

Help Center Help Center. For vectors, the length is simply the number of elements.

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 vector in a coordinate system. I saw what was meant looking at the tests. But before I was confused. Haha, it took me a couple of minutes to fully understand that it was the vector's element length and not the vector's magnitude that was needed. All your base are belong to us.

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. If you specify more than ndims A output arguments, then the extra trailing arguments are returned as 1.

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.

Extended Capabilities Tall Arrays Calculate with arrays that have more rows than fit in memory. If dim is an empty array, then size returns a 1-by-0 empty array.
