In the previous blog, we spelled out the bubble sort algorithm for putting an array of numbers in an ascending order. In this post, I am posting the matlab program. It is better to **download** the program as single quotes in the pasted version do not translate properly when pasted into a mfile editor of MATLAB or see the **html version **for clarity and sample output.

%% PUTTING AN VECTOR OF NUMBERS IN AN ASCENDING ORDER?

% Language : Matlab 2007a

% Authors : Autar Kaw

% Last Revised : November 8, 2009

% Abstract: This program shows you how to put a vector

% of numbers in an ascending order using the bubble sort method

clc

clear all

disp(‘This program shows the bubble sort method’)

disp(‘to put a vector of numbers in an ‘)

disp(‘ascending order’)

disp(‘Matlab 2007a’)

disp(‘Authors : Autar Kaw’)

disp(‘Last Revised : November 8, 2009’)

disp(‘http://numericalmethods.eng.usf.edu’)

disp(‘ ‘)

%% INPUTS

% The vector of numbers

disp (‘INPUTS’)

disp(‘Input the vector of numbers’)

A=[18 7 6 15 4 13];

disp(A)

%% SOLUTION

% Number of entries, n

n=length(A);

% making (n-1) passes

for j=1:1:n-1

% comparing each number with the next and swapping

for i=1:1:n-1

if A(i)>A(i+1);

% temp is a variable where the numbers are kept

% temporarily for the switch

temp=A(i);

A(i)=A(i+1);

A(i+1)=temp;

end

end

end

%% OUTPUT

disp(‘ ‘)

disp (‘OUTPUT’)

disp (‘The ascending matrix is’)

disp(A)

how to make we input in command window? not in editor

LikeLike

this is for array of distinct element only

meaning there should be no repeating elements

LikeLike

It will work for nondistinct elements as well.
