Help with storing values for the loop I created want to store them with where they are located on the vector

the vector is [4 1 6 9 2 1 8 3]

want to sort from smallest to biggest which I did, but I can not seem to figure out how to store them from where they were found on the vector.

Is this what you're after?

vector = [4 1 6 9 2 1 8 3];
[sorted,sortinds] = sort(vector)
sorted =
     1     1     2     3     4     6     8     9
sortinds =
     2     6     5     8     1     3     7     4

Here, sortinds gives the locations of the sorted values in the original vector vector, e.g., the first element in the sorted vector is 1=vector(2), the second is 1=vector(6), the third is 2=vector(5), etc.

The loop goes over for if statements to find the smallest value in the vector then I have to create another for if statement that stores the value from the for if statement from before and repeats that.

Your function takes an input vector, and returns two outputs, (i) sorted and (ii) indices. As I understand it, those two outputs should be (i) sorted = the elements of vector sorted into ascending order, and (ii) indices = the locations in vector of each element in sorted.

Is that understanding correct? If so, then

[sorted,indices] = sort(vector)

does exactly what you need. There would be no need to loop on anything.

On the other hand, if I'm misunderstanding things, please try to clearly explain what the function arguments are supposed to equal. In doing so, forget for a minute about how to get those outputs (e.g., don't tell me about the algorithm you think should be used), just explain what those output should be in the end.
