How to assign variables based on index position

I want to assign a variable based on index position

a = [1 1 1 1 1.6 1.1 1.1 1.6 1.1 1.1]

find(a > 1.5)

This gives me the position of those values in the array

ans =

5 8

I then want to assign them a variable such that gap1 = 5, gap2 = 8 to gap(n) = #

Following this, I want to apply these variables

getNPVI(a(1:gap1 - 1))

getNPVI(a(gap1 + 1:gap2 - 1))

until getNPVI(a(lastgap + 1:end))

Any guidance is appreciated, thank you.

For the assignment problem I would try something like that:

kk = a > 1.5;
indexes = 1:length(a);
out = a*(~kk) + indexes * kk;

For your second problem try using a Hankel matrix as an index matrix. A simple "for" loop would also do the trick.

One way:

a = [1 1 1 1 1.6 1.1 1.1 1.6 1.1 1.1]
result=find(a > 1.5) 

Now access the result data as result(1) and result(2) ..array indexing is recomended rather than different variable names
