This is the code!
function y = mysort(x)
% Emulates the Matlab internal function ‘sort’
N = length(x);
for j = N:-1:2
track = x(1);
tracki = 1;
for i = 2:j
if x(i) > track
track = x(i);
tracki = i;
end
end
x(tracki) = x(j);
x(j) = track;
end
y = x;

The function is applied in Matlab as shown:
>> y = [-10 8 -4 3 12 -15];
>> x = mysort(y);

Remove the clear all, close all, clc line.
You generally don't need to use those commands, specially not inside a function.
Note that the file mysort() is not a script, it's a function.
Also, while asking a question here, you should share your code (by copy-pasting or sharing the file) instead of posting a picture of it.

@Giha, The code seems to be working here, without that line -
x = [-10 8 -4 3 12 -15];
y = mysort(x)
y = 1×6
-15 -10 -4 3 8 12
function y = mysort(x)
% Emulates the Matlab internal function ‘sort’
N = length(x);
for j = N:-1:2
track = x(1);
tracki = 1;
for i = 2:j
if x(i) > track
track = x(i);
tracki = i;
end
end
x(tracki) = x(j);
x(j) = track;
end
y = x;
end

Please share the file mysort(). Use the paperclip button to attach.

It works here, without any errors.
x = [-10 8 -4 3 12 -15];
y = mysort(x)
y = 1×6
-15 -10 -4 3 8 12
If you get an error while running the file, I suspect there might be a duplicate file named mysort(). Please share the output of this code -
which mysort -all
