Change eigen_vector values from lua

Hi, one of the orocos components I'm using stores some properties in a eigen_vector. I would like to change these values from a lua script, possibly without having to use the marshalling. I tried v(0), v[0], v.value but it din't work. Is this possible?

Best regards, Alain

Please provide more detail on what you tried and what exactly didn't
work, and the error messages you got.

To change the value of a array property, it will take something along
the lines of:

vect=component:getProperty("eigen_vector")
vect[0]=1.5

Please also refer to the docs[1]

Change eigen_vector values from lua

Submitted by alainscialoja on Mon, 2013-05-06 16:17.

Ok, I was confused, here some more info. I want to change some properties of a Constraint Controller (CC) component from my State machine. I was initially trying from the Orocos TaskBrowser, I browse to my CC and then I try to change the value of the eigen_vector Kp:

CC [U]> Kp =                     
1
1
1
0.5
0.5
0.5
 
CC [U]> Kp[0]=0
Fatal Semantic error: Illegal use of []: eigen_vector[ int ].

Now I tried to do it from the state machine in Lua as you suggested and this is the code:

function f_eigen()
      print(" Calling f_eigen")     
      v=peertable.CC:getProperty("Kp")
      print (v)
      v[0]=0.01
      v[1]=0.01
      v[2]=0.01
end

The print works but I get an error:

Calling f_eigen
Kp (eigen_vector) = 
        1
        1
        1
        0.5
        0.5
        0.5 // Proportional Feedback Gain for output
ENTRYerror executing entry of root.NONemergency.s_TeleOp: .../thesis_ROS_LV/iBot_app/scripts/itasc_supervisor.lua:413: Variable.newindex: indexing failed, no member 1

Of course I tried indexing the vector from 1 instead of 0 but it doesn't work.

Something is missing/wroing in the typekit, thus indexing the vector
fails. Maybe if you can post (a link to) the code, someone can take a
look.

Are you using the master branch of itasc_core? I recently (March 23) pushed
a fix for the eigen_toolkit on that branch.

So it should be working if you use the latest HEAD of the master branch.

Change eigen_vector

Submitted by gianni borghesan on Wed, 2013-05-08 08:04.

Hi Ruben,
Many of us are in the devel branch, and the master has not be updated im
a while, i believe, so merging would be a little difficult...
Could you please push this fix also in the devel?
do you think this will fix also the problem with reporter?
Before it was not possible to report a eigen vector port because it
wrote down a column vector in place of a row, disrupting the formating
of the file...

Cheers, Gianni.

You could try to cherrypick the commit containing the fix (19c5466fa29),
this should be pretty straightforward. I'll leave this to you guys since
I'm depending on master for production code. What is the current status of
the devel branch? Has development settled down to consider a merge from
devel to master? How much rewriting of an application that currently uses
master would be required?

Executing the following script:
----------
require 'rttlib'

dp=rtt.getTC():getPeer("Deployer")
dp:import("itasc_core")

dp:loadComponent("reporter","OCL::FileReporting")

eigen_port = rtt.OutputPort("eigen_vector")
dp:addPort(eigen_port,"eigen_port")

vec = rtt.Variable("eigen_vector")
vec:resize(4)
vec:fromtab{0.,1.,2.,3.}
print(vec)
eigen_port:write(vec)

reporter = dp:getPeer("reporter")
dp:addPeer("reporter","Deployer")
reporter:reportPort("Deployer","eigen_port")
reporter:setPeriod(1.0)
reporter:start()
--------------

results in the following report file:
----------
TimeStamp Deployer.eigen_port.0 Deployer.eigen_port.1 Deployer.eigen_port.2
Deployer.eigen_port.3
2.58e-07 0 1 2 3
1.00008 0 1 2 3
2.00007 0 1 2 3
3.00007 0 1 2 3
----------

Is this the format you are looking for? If not I'm not sure I understand
the disruption in the format you are talking about.

Change eigen_vector

Thank you Ruben, as Gianni said I'm working on devel. Applying your commit worked for me and now I can use eigen_evctor, but I don't have write access to the repo, I'll ask Gianni to do push it. Kind regards, Alain

I believe that is quite settled at least in itasc_core and
itasc_robot_objects, while tasks could have modification in the future,
i believe.

yes
If not I'm not sure I understand
last time i tried i got
2.58e-07 0
1
2
3
1.00008 0
1
2
3
etc.
