In this article, we are going to discuss the "Inversion of a vector" in MATLAB which can be done in three different approaches that are illustrated below:
Method 1: By using flipud() function
The flipud() function is used for flipping the specified vector's elements.
Syntax:
flipud(A)
Here, flipud(A) function is used to return a vector with reversed elements of the same length of the specified vector "A".
Example 1:
% MATLAB code for inverse a
% vector using flipud()
% Initializing a vector of some elements
v = [10;9;8;7;6;5]
% Calling the flipud() function
% over the above vector "v" to
% reverse its elements
flipud(v)
Output:
Example 2:
% MATLAB code for inverse vector using flip()
% Initializing a 2*2 cell array of characters
A = {'a' 'b'; 'c' 'd'}
% Calling the flipud() function
% over the above cell array to
% reverse its elements
flipud(A)
Output:
Method 2: By using fliplr() function
The fliplr() function is used for flipping the specified row vector's elements.
Syntax:'
fliplr(A)
Here, fliplr(A) function is used to return a vector with reversed elements of the same length of the specified row vector "A".
Example 1:
% MATLAB code for fliplr()
% Initializing a row vector
v = 10:20
% Calling the fliplr() function
% over the above vector "v" to
% reverse its elements
fliplr(v)
Output:
Example 2:
% MATLAB code for fliplr()
% Initializing a 2*2 cell
% array of characters
A = {'a' 'b'; 'c' 'd'}
% Calling the fliplr() function
% over the above cell array "A" to
% reverse its elements
fliplr(A)
Output:
Method 3: By using "vector(end:-1:1)" operation
The end keyword in MATLAB is used for either finding a row or column index to reference the last element,
Example 1:
% MATLAB code for find inverse
% of vector using end keyword
% Initializing a vector of some elements
v = [10;9;8;7;6;5]
% Reversing the above vector's elements
v(end:-1:1)
Output:
Example 2:
% MATLAB code for find inverse
% of vector using end keyword
% Initializing a row vector
v = 10:20
% Reversing the above vector's elements
v(end:-1:1)
Output:
