Different elements in two 1 D array

[Nghtcrwlr]

Helloo

I am having two 1 D arrayes. one array consists of r values and other theta values. For example (See attachement) , I want to take the two r values for same theta values and so on fro other tetha valules. how is this possible?

Thanks

You did not tell us what kid of output you want, but a FOR loop should do what you need. Autoindex on the "angles" and not on the "Rs", and you'll get a 2D array.

No problem. As you can see, you have twice as many FOR loops as you actually need, but the idea is the same. 😄

Hello Tinnitus

Am having Labview version 8.2.. I coudnt open ur VI. But still I used the vi that was posted by altenbach.

anywy thnx for ur help. Is there actually a way to open the higher versions of VI in lower one?

Thnx

hello Altenbach

Thnx for your help. I was not aware of the indexing stuff.. now it wrks. but still there is some difference in final answer...

for example suppose there is only 1 value of r ; r = 3. and theta = 90,180,270,360

SO complex numbers should be when  r=3 and theta =90 (1.5708 rad) ----->0+3i . the Re part of the answers is different in two cases.  See attachmenet

I think since it is anyway zero, that difference doesnt affect, right? What could be the reason for that difference in results?

Its not possible. If you want to do so, just post here. Somebody using that higher version will convert it for your version.

done, i delete the unneeded loop

it's normal because of approximation of pi and calculation, try to use multiple of pi=3.14xxxxxxxxxxxxxxxxxxx  given in numeric palette -> pi constant

also you can modify numeric displaying  just for eyes to round values ...  (ex 3 digit after coma)

it doesn't affect standard calculation , expect in critical "asservissement" i think (translation not found)
