Diagonalize the DRMI Length Control

NB: This does not work completely, as the matrix inversion is not yet done correctly

In the $SCRIPTS/LSC directory, run

senseDRM 

This will measure the plant, giving you info along the way and putting the results into some files. The last line of screen output should give you a matlab command to run, such as

Use the matlab command: loadDRMImatrixData('DRMImatrix/DAT_090612-1244839443'); 

Run this matlab command, which will give you a tdswrite command:

Your command to copy and paste into a terminal is:


tdswrite C1:LSC-ITMTRX_92 -1.1198 \
C1:LSC-ITMTRX_b2 2.8519 \
C1:LSC-ITMTRX_d2 -0.17059 \
