= SD.M =

MATLAB toolbox for processing of SDF (StelarDataFile) files.
The whole toolbox consists of a single m file (SD.M),
so to use it, simply copy sd.m to your current working directory.
No other variables will polute your workspace.


== Usage ==

=== Initialization ===
To initialize some local variables, start with '''sd ini''' or '''sd('ini')'''.
At that that point, two global variables are created: 
 * '''SDF''' holds all mesurement data, as read from .sdf file
 * '''SDP''' holds all settings parameters, necessary to run SD toolbox

== Command list ==
{{{
 SD INI                       - initialize SD session
 SD OPEN {filename.sdf}       - open SDF file
 SD OPEN +                    - next file will be appended
 SD REOPEN                    - open last file again

 SD ZONE {i}                  - show T1 fit for zone i
 SD RECALC                    - RECALCulate all zones

 SD SHOW
 
 SD DIPS
 SD('DIPS',0, {'R','I','A'})  - 0 means all blocks,
 SD('DIPS',1:3, 'A')          - blocks 1:3, 'A'bsolute

== Parameters ==
Use these paramters to modify SD.M behavior:
{{{

SD.EP                         - End Point for FID integration (EP=0 means all)
SD.IB                         - Initial BLOCK for FID integration
SD.EB                         - End BLOCK for FID integration (EB=0 means all)
