Selection Sort algorithm solved using MATLAB Function

This video shows the implementation of the Selection Sort algorithm using MATLAB Function.

We will be glad to hear from you regarding any query, suggestions or appreciations at: programmerworld1990@gmail.com

Source Code:

function y = SelectionSort(x)
n = length(x);
for i=1:n
min_index = i;
for j=i+1:n
if x(min_index) greater_than x(j)
min_index=j;
end
end
%Swap
if(min_index~=i)
temp = x(min_index);
x(min_index) = x(i);
x(i) = temp;
end
end
y=x;
end

  1. Q:3 Write the Matlab code which will give the number of element greater than 5 in the Array A= [ 1 -6 12 4 6 8 9 2] and it will also specify the location of these elements.

    • Just change the comparison from greater_than to less_than. The modified function will be as below:

      function y = SelectionSort(x)
      n = length(x);
      for i=1:n
      max_index = i;
      for j=i+1:n
      if x(max_index) less_than x(j)
      max_index=j;
      end
      end
      %Swap
      if(max_index~=i)
      temp = x(max_index);
      x(max_index) = x(i);
      x(i) = temp;
      end
      end
      y=x;
      end

      It should work.
