linalg::vecdim

Number of components of a vector

MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.

Syntax

linalg::vecdim(v)

Description

linalg::vecdim(v) returns the number of elements of the vector .

Examples

Example 1

We define a column vector with two elements and a row vector with four elements:

v1 := matrix([1, 0]); v2 := matrix([[1, 2, 3, 4]])

linalg::vecdim gives us the number of elements, i.e., the dimension of these vectors:

linalg::vecdim(v1), linalg::vecdim(v2)

In contrast, the function linalg::matdim returns the number of rows and columns of these vectors:

linalg::matdim(v1), linalg::matdim(v2)

Parameters

v

A vector, i.e., an n×1 or 1 ×n matrix of a domain of category Cat::Matrix

Return Values

Positive integer.
