Hello everyone,

i am looking for a way to do the following without a for loop.

Suppose i have an array C of 100 elements and i have some events in the array (3 events) that i want to perform operation on.

A = [1; 20; 35;] this is the start index of those events

B = [5; 22; 55;] this is the end index of those events

how can i in one command for example do the following?

max(C(A:B)) where it should look for the max element of the event using index of A(1):B(1), A(2):B(2) and A(3):B(3)

thank u

You can use arrayfun function:

arrayfun(@(a,b) max(C(a:b)),A,B)
