Convert time stamps to binary

Hi, I really don´t have any idea how to do this..... I have a vector

a=[0.6 0.7 1.1 2.1 2.2 ....]

I want to convert it to this

b=[0 0 0 0 0 1 1 0 0 0 1 0 0 0 0 0 0 0 0 0 1 1 ......]

Sampling frequency in this example is 0.1. I am sure there is a really easy way to do this but I can´t think of anything useful.

Thanks for the help,

Roberto

Ok sorry, the 1s are indexed by a. For this reason 1 is in position 6,7,11,21 and 22 in vector b. I hope it is clearer now.

Answer 1

 b = [];
 b(round(a/0.1)) = 1

The round is necessary because of floating point precision.
