I have a list of students , every student has a grade (numeric value)
how can i order the list of those students according to their marks ,
so that the first one in the list is the one who has the highest grade
for example (let's assume that the grades are between 0 and 20)
Alex: 19
Morgan: 12
Erik: 15
Montana:13
Molko:10
Kelsie:16
the list should be lik that

Problem statement is pretty straightforward. What exactly is the issue here? Can you share what you have tried so far on this?
when it comes to order numeric values it's nor a problem but
ordering names is where i found the problem
so if it is really straightforward, please show me how

Name = {'Alex';'Morgan';'Erik';'Montana';'Molko';'Kelsie'};
Marks = [19;12;15;13;10;16];
% Create a table
InputTable = table(Name, Marks)
% Sort rows of the table
SortedTable = sortrows(InputTable, 2)
Temp_List=SortedTable(:,1)
Required_List=flip(Temp_List)
As I said, It's straighforward. Hope this helps!

Hint: Use sort().

could you please give me the command i should use because i know how to order numeric values only with this function
Just use a cell array to contain each name and corresponding grades in each row of the cell array . Sort the grades which is in the second column. Assign the second output of sort as the row subscript for the cell array thereby sorting your cell array according to the given homework. If you are still not able to figure out, post the code that you tried to get further help.
