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. For example, find the lengths of the first and third dimensions of A.

Find the length of each string in str. Use strlength , not length , to determine the number of characters in each element of a string array. Create a character vector. To return the number of characters in the character vector, use the strlength function. Input text, specified as a string array, a character vector, or a cell array of character vectors. To find the length of the largest array dimension of str , use the length function, not strlength. Code units are bit sequences for encoding characters of a character encoding system. In some character encodings, such as UTF, there are some characters that are encoded with multiple code units. If you have a string or a character vector that contains such characters, then the number of code units is greater than the number of characters. This function fully supports tall arrays.

Size of Table.

Object to examine, specified as a single parallel object or parallel object array. A parallel object can be a distributed , codistributed , gpuArray , Composite , parallel.

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. Use the structfun function to apply length to each field. To find the number of characters in a string or character vector, use the strlength function.

Data Types: double single int8 int16 int32 int64 uint8 uint16 uint32 uint64 logical char string struct table timetable cell categorical datetime duration calendarDuration. The number of dimensions in an array is the same as the length of the size vector of the array. This function fully supports tall arrays. For more information, see Tall Arrays. This function fully supports thread-based environments.

Toggle Main Navigation. If you have a string or a character vector that contains such characters, then the number of code units is greater than the number of characters.

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.
