I´m currently working into LiveLink for Matlab and COMSOL and encountered a problem when trying to extract the system matrices (for model reduction) when applying the "mphstate" command. On the one hand i´m not able to figure out what the "coords2" component for the domain point probe is about, probably leading to an error like:
model.param.set('Qinput','4010.7[W/m^3]'); %% Setting the heat source as parameter comp1 = model.component('comp1'); comp1.physics('ht').feature('hs1').set('Q0',1,'Qinput'); pdom1 = comp1.probe.create('pdom1','DomainPoint'); pdom1.setIndex('coords2','0.4',0,0); pdom1.setIndex('coords2','0.6',0,1); time = model.study('std2').feature('time'); time.set('tlist','range(0,50,2e3)'); M=mphstate(model,'sol2','out',{'A','B','C','D'},... %% Getting the matrices 'input','Qinput','output','comp1.ppb1');
Error using mphstate Java exception occurred: Exception:
com.comsol.util.exceptions.UnexpectedServerException: java.lang.ArrayIndexOutOfBoundsException: 2
(rethrown as com.comsol.util.exceptions.FlException)

Also the tutorials within the manual do not work ... which is quite strange. I guess it´s just a trivial mistake done by me, but i can´t figure out its source. Greetings.
