function mpg = sort_cars(N)
wgt=[cars.Weight]' ;
mpg1=[cars.MPG]';
mpg2=zeros(1,length(wgt));
for i=1:length(wgt)
[wgt1 inx]=max(wgt);
mpg2(end-i+1)=mpg1(inx);
wgt(inx)=0;
end
mpg = mpg2(1:N);
end
this is my code for the problem 44952 but it is not executing..showing error
Below is one of the test case..for the above mentioned problem..
N = 5
load(fullfile(matlabroot, 'toolbox/stats/statsdemos', 'carbig.mat'));
Model = strtrim(string(Model));
cars = table(Model, MPG, Horsepower, Weight, Acceleration);
save cars.mat cars
assert(isequal(sort_cars(N),[35; 31; 39.1; 35.1; 31]));
can anyone plz help me in solving this problem...
Thank you

When you load data into the base workspace like you do, then the variable cars will not be sured with the inside of the function. It is possible to share variables into a function, but only for nested functions.
