Selecting array values
I have two arrays DIST(1:NCOF) and X(1:NX)

Code:
Let NCOF = 5 and NX = 15, with

DIST = [10 20 30 40 50] and
X = [ 30.3 40.4 50.3 60.6 70.4 80.5 90.3 100.7 110.4 120.7 130.6 140.5 150.5 160.2 170.4]

I want to create an array that puts a zero if DIST is outside the region in X, otherwise putting 1.

In this example I should get

Code:
RES =  [0 0 0 1 1]
Using DIST = [150 160 170 180 190] would give RES = [1 1 1 0 0]

The values in DIST will be consecutive and they will get out of range from only one side, either to the right or to the left side of DIST.
This can help to doing the check more efficiently, than checking every value.

pbuilder-dist-simple

PBUILDER-DIST-SIMPLE(1) 				      General Commands Manual					   PBUILDER-DIST-SIMPLE(1)

NAME

       pbuilder-dist-simple - simple multi-release pbuilder wrapper

SYNOPSIS

       pbuilder-<dist> operation [...]

DESCRIPTION

       pbuilder-dist-simple  is  a  wrapper  that makes it easy to use pbuilder with chroots for many different Ubuntu distributions.  If you need
       more features than pbuilder-dist-simple provides, have a look at pbuilder-dist(1).

USAGE

       Create one symlink to pbuilder-dist-simple for each distribution for which you want a build environment, naming them like "pbuilder-lucid",
       "pbuilder-natty", etc.

       Replace operation with the action you want pbuilder-dist-simple to do (create, update, build, clean, login or execute).

EXAMPLES

       pbuilder-natty create
	      Creates a pbuilder environment for Ubuntu Natty.

       pbuilder-lucid update
	      Updates an existing Ubuntu Lucid environment.

       pbuilder-lucid build ./sample_1.0-0ubuntu1.dsc
	      Builds the specified package on an already existing Ubuntu Lucid environment.

FILES

       By default, pbuilder-dist-simple will store all the files it generates in ~/pbuilder/.  This can be changed by modifying the BASE_DIR value
       on the top of the script to any other directory you want.  If the directory doesn't exit, it will be created at runtime.

SEE ALSO

       pbuilder(1), pbuilderrc(5), pbuilder-dist(1)

AUTHORS

       pbuilder-dist was originally written by Jamin W. Collins <jcollins@asgardsrealm.net> and Jordan Mantha <mantha@ubuntu.com>, and	this  man-
       page by Siegfried-A. Gevatter <rainct@ubuntu.com>.
