which two members from s vector restricted a random number

Hi all,

I have a vector like s=[200 278 434 590 746 903 1059 1215 1371 1450]. I want to determine which two members from s vector restricted a random number like b=300 ? for example 300 is between 278 and 434.

How can I write such program?

thanks in advance,

s = [200 278 434 590 746 903 1059 1215 1371 1450];
b = 300;
[dummy, index] = histc(b, s);

Or:

index = find(s < b, 1, 'last');   % or <= ?

Because the values of s are sorted, it is enough to find one index.
