RUtil

RUtil is a convience namespace for use with ROOT. There are several sub-namespaces for use with different things. One is an FFT namespace that uses the ROOT wrapper of FFTW to do FFTs and make spectrograms and stuff like that. This part I think is pretty fast; FFTW optimizes the speed of the FFT on the first one of a certain size and then the subsequent calls are super fast. Eventually i'll expand this to cache multip. Another is an SVD namespace that does SVD type matrix operations and decompositions. This part is pretty slow compared to more native implementations like using GSL or something but it works OK. Most importantly, there are lots of utilities for analyzing RF waveforms, mostly using TGraphs. there are utilities for shifting, stretching, aligning, slicing, stacking, averaging TGraphs etc., which are useful for RF analysis. There are also some built in canvas and histogram title settings that make the default plots look less like garbage.

some stuff might be broken and things might not work right and I add to this regularly. I will do my best to not break backward compatibility if i add stuff, but no promises.

installing

basic install, will put things in the appropriate places in /usr/local

cd /path/to/your/desired/source/dir
git clone https://github.com/prchyr/RUtil.git
cd RUtil
./install.sh

or, to install somewhere else

cd /path/to/your/desired/source/dir
git clone https://github.com/prchyr/RUtil.git
cd RUtil
export RUTIL_INSTALL_DIR=/path/to/your/desired/install/dir
./install.sh

and then don't forget to reference RUTIL_INSTALL_DIR in the appropriate places in your .bashrc.

using

To use in your c++ programs, do

#include <RUtil.hh>

in your programs, and compile against the library with the flag

-lRUtil

To use inside of the ROOT interpreter (either command line or with macros) add these lines to your rootlogon.C:

gROOT->ProcessLine(".L RUTIL_INSTALL_DIR/lib/libRUtil.so");
gROOT->ProcessLine("#include <RUtil.hh>");

where you have replaced RUTIL_INSTALL_DIR with the correct path (for the default installation, it would be /usr/local/. Or if you have set this variable globally, it might work as-is.

documentation

currently, functions are just defined in the header. there is also some description, especially of FFTs, in the source. I'll try to add more.
