kalman icon

[VineetA]

I dont know how but my kalman vi changed into something else and i dont know how to undo it. I looked up at the icon option which was previously static but not it is at express and the static option is not no longer available. Help.

It'd probably elp if we could at least touch the code and see if anything is strange.  If you don't want to share your whole code, you can remove the stuff you don' want us to see and post what's left.

Its not about the code. Its just the icons of kalman filter and extended kalman filter. When i pick and drop the icon onto the block diagram(new vi or any other vi), it shows the above icon not the normal one.

The reason to ask to see code is that few posters (you, included) provide enough information for us to help you, and usually seeing some code gives us a lot of useful clues, such as (a) What Version of LabVIEW are you using, and (b) What Toolkits or Modules (other than Core LabVIEW) are you using.  Note that there is no Kalman filter in LabVIEW itself -- it is in one of the add-on Libraries (and one that I have not loaded, myself).

My advice would be to take the "Belt and Suspenders" approach -- post your code and answer the two questions above.

If you knew what the problem was, you wouldn't be asking.  Please, don't tell us what the problem is if you don't know.

In addition to what was stated as reasons that seeing your code helps, consider this.  You're making the assumption the behavior isn't isolated to your installation.  What if it is?  What if when we open your code, we see what you expect to see rather than what you ARE seeing?  Don't you think this is a key piece of information?

You've given us almost nothing to work with.  Why do you think that makes sense?  If I told you the final result of a complex calculation was 42, would you be able to tell me all of the steps that brought me to that value instead of .004200420042?  That's essentially what you've asked us to do.  When we ask to see the steps, you pout that we're focusing on what brought you to the result rather than the result.  EVERYTHING is about either your code or your environment.

The Kalman Filter is a feature from the LabVIEW Control Design and Simulation Module. The function is a Simulation subsystem function and this function can be 'dropped' inside or outside the Control and Simulation Loop.

What you are seen is how we render the function output Control and Simulation Loop. The reason for this difference is because we need a way to add the 'solver' configuration to the connector pane and we can't do that with the other icon styles (Static and Dynamic). So, the only option output the Control and Simulation Loop is " Text Only" or "Express".
