How to locate the index of the maximum value in a given range

Suppose we have two vectors

t= [ 1 2 3 4 5 6 7 8 9 10 11]; % time values

y = [1 2 3 4 5 7 5 4 3 2 1]; % a dependent variable

We can find the max value of y, by max(y), here it is 7. How can we locate the index i of 7 and value the corresponding value of t at idex i? Basically I am trying to locate a peak maximum and its corresponding time.

Thanks

Use the 2nd output of the max function:

[p,i] = max(y);

p is the max value, i is the index of the max value

t(i) is the value of t at the same point as the max of y

I don't understand your question. t(i) is the time associated with the max value of y. Isn't that what you wanted?
