how to find size of bundle?

[akash189]

hi all,
i am making a vi in which the input is a bundle containing unknown number of elements (string and double 1d and 2d arrays), i want to unbundle it and then write in matfile format, i need to know how many elements and the type of each element and then i can write them using a for loop and writing for each element.
please give me suggestion how to do it and if somebody has any example please attach.

thank you

You can create an indicator for the cluster, create a property node for the indicator, select Controls[] and that will be a 1D array. Use the Array Size to tell you the size of the array. You can always hide the cluster indicator.

Hi,

I'm not sure if you already have the cluster made or not... but an easy way to find and display what is inside, is to right click the cluster icon on the back panel > create > indicator.  This will automatically configure the indicator so that it dispalys everything correctly.

Also if you need to see the elements individually, use the unbundle command.  Again to create indicators for each element of the unbundle, you can right click > create > indicator, like I have shown in the attached image.  This image demonstrates how to create an numeric indicator off of the array size module.

Hope that helps.

hi,
as I want to write elements of the bundle in matfile - i have different vi for writing an array of string and double numbers-
if I unbundle i get all the elements of the bundle
i want to know how can i take the elements of the bundle one by one and determine their type and then send them to the corresponding vi?
if i can access then one by one in a loop and can determine their type then i can use a event structure to send each element to differnt vi
so i just need to know how to access one by one and find their type
i now have labview 8.2
thanks a lot for the help

Okay I see what you mean now.  Well if all the clusters are the same (same order/configuration).  Then you might be able to use a cluster to array function, which will send all of your cluster elements into an array.  Then use a for loop to index each element of the cluster, which can be followed by a case statement, to access for the corresponding index, which will allow you to execute the appropriate action.

Have a look at the image.  If I understand you correctly, then I think it should do what you're looking for.

If you need help with the code, let us know!
