Nobody would do this:
[ .25; .05; .10; .01; ]

[~,b]= max(sum((a.*[.25,.05,.1,.01]),2))

Test	Status	Code Input and Output
1	Pass	a = [1 2 1 15]; b = 1; assert(isequal(most_change(a),b)) values = 0.2500 0.0500 0.1000 0.0100

6	Pass	% There is a lot of confusion about this problem. Watch this. a = [0 1 0 0; 0 0 1 0]; c = 2; assert(isequal(most_change(a),c)) % Now go back and read the problem description carefully. values = 0.2500 0.0500 0.1000 0.0100
