Question

*MATLAB CODE*

3)Write a function 'mydsort' that sorts a vector in descending order (using a loop, not the built-in sort function).

4)write a function that will receive a vector and will return two index vectors: one for ascending order and one for descending order. Check the function by writing a script that will call the function and then use the index vectors to print the original vector in ascending and descending order.

**Please make sure they work. I have found other examples of these however none of them are working properly. I will rate if the program runs properly.

Answer 1

1)

function A=mydsort(A)
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
end
