interpolation

[Guest_imported]

I have a file with the following format:


dist1 dist2 dist3 dist4 ...
--------------------------------------
stress1 stress2 stress3 stress4 ...

given a stress value, I can get the range. If the given stress is between stress3 and stress4 I can print out the line they came from, their column numbers and their values, but I have yet to figure out how to use that information to also obtain the distance values from those same columns (two rows earlier).

Any help would be appreciated.

What distinguishes a dist line from a stress line (or are there only 3 lines in the file)? How is the "given stress" specified? Post a small sample of the input file and I am sure someone will help you. CaKiwi

This will be a subroutine from another script which will pass the "desired stress" to this code.

Pretend there are only three lines in the file, but actually there are 27, but I use a for loop to look at every third line until I find a stress lower than the desired followed by a stress higher than the desired on a given line.

Ok, then in your loop for every first line of 3 execute the statement

  n = split($0,dist," ")

The array dist will then contain the dist values, i.e. dist[1] will contain the first value, dist[2] will contain the second value up to dist[n] which will contain the nth value which you can use to match with the corresponding stress value.

Hope this helps. CaKiwi
