MATLAB Function Reference

isvector

Determine if input is vector

Syntax

• tf = isvector(A)
  

Description

tf = isvector(A) returns logical 1 (true) if A is a 1-by-N or N-by-1 vector where N >= 0, and logical 0 (false) otherwise.

The A argument can also be a MATLAB object, as described in MATLAB Classes and Objects, as long as that object overloads the size function.

Examples

Test matrix A and its row and column vectors:

• A = rand(5);
  
  isvector(A)
  ans =
       0
  
  isvector(A(3, :))
  ans =
       1
  
  isvector(A(:, 2))
  ans =
       1
