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.

Dimension to measure length of vector v , specified as a positive integer scalar. Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 logical. Size of vector v , returned as a nonnegative integer scalar or a two-element vector. When dim is not specified, sz is the two-element vector [length v , 1]. When dim is 1, sz is a scalar equal to the length of v.

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.
