I am currently finishing the course "MatLab Fundamentals" but I cannot reach 100% because in "Increasing Automation with Functions > Creating and Calling Functions > (5/5) Create and Call Local Function", Task 1, I’m not able to answer in the correct way to that Task. Since I thought I answered right, I checked the solution and it was the same as my script; however even copying and pasting the solution script and trying to submit the Task, it appears to be "Incorrect" (Is pp calculated from the function paretoperc?). I can’t understand if I’m missing something or if there’s some kind of problem since also the solution script doesn’t work. What can I do?
Here’s the code:
Task 1
pp = paretoperc(medals)
Task 2

Further Practice

function pp = paretoperc(x)
% Cumulative contribution of data points (in order)
cc = cumsum(sort(x(:),"descend")); % (:) to ensure column vector
cc = 100*cc/cc(end); % Normalize to percentage
% Corresponding percentiles (column vector to match cc)
pct = (1:numel(x))’;
pct = 100*pct/numel(pct); % Normalize to percentage
% Find the number of data values needed so that
% P% of the data is in (100-P)% of the values
idx = find(cc >= (100-pct),1,"first");
pp = cc(idx);
