ScilabDataAnalysisTemplate

This is a template for data analysis with scilab.
It is mainly intended to facilitate use and minimize potential errors by :

• enforcing a consistent directory structure
  For each novel data analysis problem, the idea is to create a novel directory containing at least

  • WRK: working directory for the data analysis problem
    • DAT: data used as input for analyses
    • RES: results of analyses
    • PRG: scripts and functions for the analyses

• compiling all functions in PRG when you run main.sce
  This is handy, though you must re-run main each time you modify a function. The compilation is done in InitTRT.sce

• providing a minimum set of ingredients for time series processing
  • LIB_Signal
    • AmplitudeSpectrum.sci Amplitude spectrum of a signal from fft
    • LowPassButtDouble.sci Low pass filters a signal with a dual-pass second-order Butterworh iir filter
    • fltsflts.sci Applies a filter forward and reverse in time (zero phase shift filtering)
    • gradient.sci One-dimensional gradient of a signal (first central difference)
    • unwrap2pi.sci Unwraps phase by changing jumps greater than pi to their 2*pi complement
  • FourrierAnalysis.sce
    Illustrates the use of the library

Usage

• (Clone or) download the repository
• On your computer :
  • Open main.sce with scilab editor (SciNotes)
  • Run the script (press F5, or click the button with a triangle)

Notes :

• You first need to install Scilab... For OSX users: please go directly to the guidelines provided by the University of Technology of Compiègne (link on scilab's page) and follow thme step by step.
• Double click on main.sce might not work... depending on your OS.
  Opening files from SciNotes always works (File menu -> open).
• Do not modify the names and organisation of the directories
  The DAT+PRG+RES structure is expected when initialising in InitTRT.sce
