Welcome to the Bubble Sort in Matlab page! Here, you'll find the source code for this program as well as a description of how the program works.
function result_string= bubble_sort(array_string)
%array_string - string containing unsorted input
%result_string - sorted result
%input validation
if (nargin==0)
%if there was no input
result_string = 'please provide a list of at least two integers to sort in the format "1, 2, 3, 4, 5"';
return
elseif length(array_string)<2
result_string = 'please provide a list of at least two integers to sort in the format "1, 2, 3, 4, 5"';
return
else
%build array
%replace all spaces with empty character
array_string(isspace(array_string)) = [];
array = [];
count = 1;
%iterate over the string, increment index by 2
for i = 2:2:length(array_string)
if ~isnumeric(str2double((array_string(i-1)))) || ...
array_string(i)~=','
result_string = 'please provide a list of at least two integers to sort in the format "1, 2, 3, 4, 5"';
return
else
array(count) = str2double(array_string(i-1));
count= count + 1;
end
%add the last number
if isnumeric(str2double((array_string(length(array_string)))))
array(count) = str2double(array_string(length(array_string)));
else
result_string = ...
'please provide a list of at least two integers to sort in the format "1, 2, 3, 4, 5"';
end
end
end
%to keep track of whether any changes have been made on each pass
flag = 1;
while flag==1
flag = 0;
for i = 1:length(array)-1
if array(i)>array(i+1)
temp = array(i+1);
array(i+1) = array(i);
array(i) = temp;
flag = 1;
end
end
end
%convert to string
result_string = num2str(array);
%replace space with ', '
result_string = regexprep(result_string, '\s+', ', ');
end
