Write for logical value Matlab

Let's say T=1:20 ; P=[2 6 9 11 15 19].

How to write a logical value for P in range T?

The answer I want is: flag= [0 1 0 0 0 1 0 0 1 0 1 0 0 0 1 0 0 0 1 0].

Use ismember made for exactly this task -

ismember(T,P)

For the fun of it, an alternative to Hoki's answer:

T(P) = 0;
flag = ~T

This sets all values that are in P equal to zero, and then checks if the values in T is 0 or not. This of course has the downside that it overwrites T. Note: I would go for Hoki's answer!

You can define a logical vector flag the size of T, then use P as an index vector of the flag to raise to true:

T=1:20 ; P=[2 6 9 11 15 19] ;

flag = false(size(T)) ;
flag(P) = true ;

flag =
     0     1     0     0     0     1     0     0     1     0     1     0     0     0     1     0     0     0     1     0
