Generate Random numbers

[Rambo333]

Hello All,

I have searched the forum and have realised, there are lot of random number generation ideas, however i have a different question, best explained by the attachment.

I want to have unique outputs.

your inputs are appreciated.

You need to compare the previous output with the new one; and skip it when the output is the same.

Instead of focussing on changing the output.. i would like to change the random input in such a way that it always picks a unique line.

My output in my program will be hundreds of line, and so i would not like to mess around.

Please let me know, if you need any more inputs

Thanks

Yep better ways to do this

If I understand correctly (from your code) you want to shuffle the lines randomly See below

For improved randomness you ca generate a random seed to input to Riffle.vi

I haven't seen your code because i'm using LV2009 but I think the attached vi will do want you want.

I wanted to do something with the shift registers and converting my string to an array.... but my program was not very convenient to do so...

Thanks !!!

It works like a charm...

@ Jeff..

I will implement your style and see the results.

Thank you

I agree with Jeff that riffle is a cleaner solution:

... now if only riffle would also accept an array of strings directly ... 😉

... in the meantime, try this. 😄

If you only have LabVIEW base (no riffle!), you could do as follows (taking advantage that clusters are sorted in element order):

I'm thinking Randomize 1D Array will suffice  Thanks for point it out- (guess what just hit my reuse library?)
