How to find a series of 'next max' and their indices in an array of numbers?

Hi,
Suppose I have an array of numbers.
I want to find all the numbers, and their indices, which are largest then all previous ones.
For example, for the array:
X = [ 1 2 5 3 4 7 2 3 10 3]
I will get:
Largest: [1 2 5 7 10]
Indices: [1 2 3 6 9]
Sure I can solve it with a 'for' loop.
What will be the fastest way to do it in Matlab?

use cummax to find the cumulative maximum, then play with the solution using unique
>> Y = cummax(X)
Y =
1 2 5 5 5 7 7 7 10 10
>> [largest,index] = unique(Y)
largest =
1 2 5 7 10
index =
1
2
3
6
9
