=====
thLib
=====

These utilities contain a number of general purpose routines for data
analysis, especially for working with 3D-data.

Noteworthy are:

savgol
======
Savitzky-Golay filter, for smoothing data, and for calculating derivatives


regress
=======
Python implementation of the Matlab function "regress" function. Calculates
best-fit values, as well as confidence intervals.

Rotation Matrices
=================

These come in two versions: the rotation matrices in numbers (in "RotMat");
and the symbolic rotation matrices (in "RotMat_s")

RotMat
------

Rotation matrices, for rotations about each coordinate axis.

E.g. RotMat.R1(30) gives you the rotation matrix for a rotation of 30 deg
about the 1-axis.


RotMat_s
--------

Rotation matrices, when working with symbolic code.
E.g.

    R1 = RotMat_s.R1_s()
    R2 = RotMat_s.R2_s()
    R3 = RotMat_s.R3_s()
    R_Fick = R3 * R2 * R1

UI
==

User interface routines. I have tried to stay close to the MATLAB originals:

- getfile
- savefile
- getdir
