MATLAB allows creating two types of vectors — . Row vectors ° Column vectors Row Vectors Row vectors are created by enclosing the set of elements in square brackets, using space or comma to delimit the elements. r= [7891011] MATLAB will execute the above statement and return the following result - Column Vectors Column vectors are created by enclosing the set of elements in square brackets, using semicolon to delimit the elements. c= [73 8; 93; 10; 11] MATLAB will execute the above statement and return the following result - Referencing the Elements of a Vector https://www.tutorialspoint.com/matlab/matlab_vectors.htm 413 10/31/21, 4:21 PM MATLAB - Vectors You can reference one or more of the elements of a vector in several ways. The it” component of a vector v is referred as v(i). For example - v=[ 13; 2; 35 4; 5; 6]; % creating a column vector of 6 elements v(3) MATLAB will execute the above statement and return the following result - ans = 3 When you reference a vector with a colon, such as v(:), all the components of the vector are listed. v=[ 13 2; 33 4; 5; 6]; % creating a column vector of 6 elements v(:) MATLAB will execute the above statement and return the following result - ans = AuRWNR MATLAB allows you to select a range of elements from a vector. For example, let us create a row vector rv of 9 elements, then we will reference the elements 3 to 7 by writing rv(3:7) and create a new vector named sub_rv. r= [12345678 9]; sub_rv = rv(3:7) MATLAB will execute the above statement and return the following result - sub_rv = Vector Operations In this section, let us discuss the following vector operations — https://www.tutorialspoint.com/matlab/matlab_vectors.htm 213
