function to display name

hey, i'm trying to create a function that will find from a structure all the car that have horsepower above 200 and display their model names from the structure.

But when I buit it, its show the names only with a space and blank names between them.

can you help me fix it?

I used the carsmall.mat database

function result = best_horsepower2(stru);
for i=1:size(stru.Horsepower,1);
    if stru.Horsepower(i,:)> 200;
        big(i,:)= stru.Model(i,:);
         result=big;
    end
end

that is because while storing the result in big you are using the index i

please try below code it might help

function result = best_horsepower2(stru);
%intialise a count vector for storing the results hence you can avoid blank
%space
count = 1;
for i=1:size(stru.Horsepower,1);
    if stru.Horsepower(i,:)> 200;
        big(count,:)= stru.Model(i,:);
         result=big;
         count = count + 1;
    end
end
