while loop performance improvement

Hello everyone,

What is the alternative of while loop for the example:

rate = 2;

while (k <= period)

sum = sum + array(k,2);

k = k + rate;

end

Thanks.

I don't know the starting value of k, assuming it is 1

idx = 1:rate:period
mysum = sum(array(idx,2)); % note that sum is the name of a matlab function

Thank you.

maxDuration = 0;

while (k <= period)

if( myArray (k,2) > maxDuration)

maxDuration = myArray (k,2);

end

k = k + rate;

end

If I make it more complex with if statement like that, how can I use that idea ?
