Full Discussion: column space
Operating Systems AIX column space Post 302213111 by bakunin on Wednesday 9th of July 2008 08:36:26 AM

I am going to transfer this thread to the "shell scripting" forum, as it belongs there.

If the input varies, as you say, you have to find a constant pattern to express it. If - for instance - the place where you want to insert a second space is the first place where a "3" and a "5" are separated by a blank then the expression to match this would be

Code:
sed 's/3 5/3  5/'

which would mean "search for the first occurrence of "3-space-5" and replace it with "3-space-space-5".

If, also for example, it is the space between the first two "words" in a line, than the expression would have to be:

Code:
sed 's/ /  /'

This means: search for the first occurrence of "space" and replace it by "space-space". This way "xxx-space-xxx" would become "xxx-space-space-xxx" and "xxxxxx-space-xx" would become ""xxxxxx-space-space-xx".

And so on and so forth. get a book about regular expressions and it will teach you how to do that.

I hope this helps.

NAME
curl -- curl operator SYNOPSIS
form(const space V, const space& M, "curl"); DESCRIPTION
Assembly the form associated to the curl operator on finite element space. In three dimensions, both V and M are vector-valued: / | b(u,q) = | curl(u).q dx | / Omega In two dimensions, only V is vector-valued. The V space may be a either P2 finite element space, while the M space may be P1d. See also form(2) and space(2). EXAMPLE
The following piece of code build the divergence form associated to the P2 approximation for a three dimensional geometry: geo omega("cube"); space V(omega, "P2", "vector"); space M(omega, "P1d", "vector"); form b(V, M, "curl"); while this code becomes in two dimension: geo omega("square"); space V(omega, "P2", "vector"); space M(omega, "P1d"); form b(V, M, "curl"); SEE ALSO
