Mysort script error issue

I am asking this question after quite some time since I have used Matab.

This is given mysort.m

and i am trying to drive to

but i am getting error on line4

can some one explain why am i getting error and, how to debug them?

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.

Joshi!

I tried to removed them and got same error!

Also Thank you for letting me know!

@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

@Dyuman Joshi I must be doing something wrong

I am still getting

this error

Error in mysort (line 4)

N = length(x);

Thank you for helping me out,

I am trying to learn matlab this year

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

Here is the attachment!

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
