Hello,
so first, instead of swapping places in the else part, you are replacing vec(i) with vec(i+1). This is changing our vector and not sorting it. Try to swap places of the two elements.
Second, our first and second if-condition is not changing anything and can thus be left out.
Third, you are only going through our vector once. This will not ensure that the vector is completely sorted. You have to repeat this loop until the vector is fully sorted.
Maybe a look at different sorting algorithms will help you. The one you are tiring to use is called: Bubble sort
This is one possible solution for the problem:
function [sorted] = mySort(vec)
vec = [4 5 2 3];
l = length(vec)-1;
swapped = 1;
while swapped ~= 0
swapped = 0;
for i=1:l
if vec(i)>vec(i+1)
zw = vec(i);
vec(i)=vec(i+1);
vec(i+1)=zw;
swapped = swapped +1;
end
end
sorted = vec;
end
end
Cheers
