Changes To Be Made From LabVIEW 7 VI To 11 VI

Highlighted

 

 

In the attachment I have a LabVIEW  VI written in LabVIEW 7. It works fine in that version, but when I try to run in LabVIEW version 11.0.1, it does not work. So, can any one suggest me what are the changes that I have to make in order to run in LabVIEW 11?

 

Thanks!

Hi Romai,

               Better post it in the Version Conversion Board

               I don't know making any changes in the older version can make it work in a newer version.

Please post the real VI.  I am not going to download a Word document just to look at a picture of some code.

Ok, so what about this VI isn't working?

Yeah!

 

If I write the same code(VI) in LabVIEW 11 it does not show me those results, instead a smaller black window.

Thanks.

My first guess would be to replace those multiplies with multiplies.  The versions currently there are to keep compatibility with older versions.  If you replace with the current, it just might work for you.

crossrulz,

 

i think that is exactly his issue. Using those deprecated functions:

creates this image:

Replacing the last multiplication only with the current version of "multiply":

Multiply Current Version.PNG

 

creates this image:

I found out, that the current version of "multiply" obviously does work the same as "A x B.vi" from the matrix-palette:

AxB.PNG

whereas the deprecated version handles the matrix as a simple array (multiplying index per index).

So i would consider the old, deprecated version as bug when talking about matrix'es and the new behavior as fix for it. Obviously (overlay tells us so) this fix was implemented with 8.0.

 

hope this helps,

Norbert

Norbert,

 

Thanks for your concern.

 

I hope you are right because it seems that the problem is with the multiplication node. Also because when I am multiplying

the image(hologram) with a circular function, it should give me a circular image.

 

Thank you once again!

If i am correct, you are running into some misunderstandings, so i want to clear some things up:

1.) A hologram is a three dimentional image. It requires lasers and interference for creation and i am not aware that i ever saw one on a monitor....

2.) You are working with matrix. Images are, simplified, 2D arrays with color/brightness as values. So using Linear Algebra (matrix) seems not correct if modifying image data. I suggest you to NOT use matrix but to go for generic 2D arrays. Tip: Insert "Matrix to Array" after your creation step. Your program will run as it did with LV 7.1.

 

hope this helps,

Norbert
