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 size of the table. Although the BloodPressure variable contains two columns, size only counts the number of variables. Input array, specified as a scalar, a vector, a matrix, or a multidimensional array. Queried dimensions, specified as a positive integer scalar, a vector of positive integer scalars, or an empty array of size 0-by-0, 0-by-1, or 1-by If an element of dim is larger than ndims A , then size returns 1 in the corresponding element of the output. If dim is an empty array, then size returns a 1-by-0 empty array. Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint List of queried dimensions, specified as positive integer scalars separated by commas.

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. Each function provides unique insights into the structure of vectors, offering versatility in different scenarios. The size function in MATLAB is a versatile tool that can be applied to arrays, matrices, and vectors to retrieve their dimensions. When applied to a vector, the size function returns a two-element row vector containing the number of rows and columns, respectively. For a vector, the number of columns is always 1. Here, A is the vector or matrix for which you want to determine the size. The function returns a 1-by-2 matrix, where the first element represents the number of rows, and the second element represents the number of columns. In this example, we work with a basic vector vector containing four elements.
