Hi Yang,<br>
<br>
The "Integrated Spectral Analysis Workbench"
(<a class="moz-txt-link-freetext" href="http://www.pns.anl.gov/computing/isaw">http://www.pns.anl.gov/computing/isaw</a>) is written in Java and has a
number of classes that may be useful to you. Specifically,<br>
<br>
...gov/anl/ipns/MathTools/lattice_calc.java <br>
provides some generally useful calculations, such as factoring UB,
getting lattice parameters, etc.<br>
<br>
<br>
.../gov/anl/ipns/MathTools/LinearAlgebra.java<br>
provides basic linear algebra routines, including finding a matrix that
best maps a list of calculated peak positions to/from (h,k,l) values.<br>
<br>
<br>
.../DataSetTools/instruments/SampleOrientation.java<br>
represents goniometer angles Chi, Phi, Omega<br>
<br>
<br>
.../DataSetTools/instruments/IPNS_SCD_SampleOrientation.java<br>
represents using the sign conventions of the IPNS SCD.<br>
<br>
<br>
These, and some related basic classes for vectors and matrices might be
helpful. If you have any questions regarding these classes in ISAW,
please contact me.<br>
<br>
Regards,<br>
Dennis Mikkelson<br>

developing control program for TAS and Single
crystal machine. This program is being developed in Java code, so I
just
think if anyone has done the same job for the UB matrix calculation in
Java and
can share the code with us that will be greatly appreciated and save a
lot of
our time to recode the same thing. Thanks,</span></font></p>
