Sort using flow control

I am new to MATLAB...first assignment and I have been tasked to build a MATLAB function that is to sort an array of numbers using flow control (smallest to largest). Then I am supposed to return the argument in a new similar array. Can anybody help me at least get started with this task?

This is how I would do the sorting:
x = randi(20,50,1);
x = x(:);
srtd = [];
for k1 = 1:length(x)
[sx,ix] = min(x);
srtd = [srtd; sx];
x(ix) = [];
end
The ‘srtd’ array would be the returned output.

My pleasure!
You said ‘array’ and I read ‘vector’. This corrects my oversight.
This will work for an (NxM) matrix:
x = randi(50,20,2); % Argument
[ar,ac] = size(x);
for k1 = 1:ac
svct = [];
xa = x(:,k1);
for k2 = 1:ar
[sx,ix] = min(xa);
svct = [svct; sx];
xa(ix) = [];
end
srtd(:,k1) = svct;
end
Run it and see if it works for you. The returned array ‘srtd’ is the same size as ‘x’, the input argument matrix (or vector). If you want to sort in descending order, replace min with max.
