Example 1  

Matlab






% MATLAB code for getting the position 
% of element 4
X = [2 4 4 5 6 4]; % Initializing an array 
% of some elements
  
% Calling the find() function to find 
% the position of 4
Position_of_4 = find(X==4)

Output:

Example 2 

Matlab




% MATLAB code for getting the position 
% of element 4 in terms of rows and columns.
X = [2 4 4 5 6 4]; 
  
% Calling the find() function to find 
% the position of 4 in terms of rows 
% and columns
