I would like to write a code to calculate if a array, for example:

[6 7 4 8 9] has maximum elements above 5 (this number will be equal to number of elements) or not.

Here 4 out 5 elements are above 5 so the output will show "max elements greater than 5".

In case the array was [2 3 5 8 9] 3 elements are less than or equal to 5(output: "max elements less than 5" ).

Please help construct this code.

Are you trying to determine if most of the values in the vector are greater than or equal to 5? That's how I understood the description but your 2nd example doesn't follow that rule so I'm confused.

在 MATLAB Online 中打开

a = [6 7 4 8 9];
val = numel(a);
if sum(a >= val) > val/2
    disp(['Max elements greater than or equal to: ' num2str(val)]);
else 
    disp(['Max elements less than: ' num2str(val)]);
end
