How do you state the range for each row?

[Shalins]

Hi Friends,

I'm having difficulting in setting a range of numbers for each row in a 2D array.  The description of the program is listed below:

A VI that outputs a 2D array with 10 rows and 5 columns. The first row should contain five random numbers in the range 0 to 1, second row numbers in the range 1-2..and so on to the tenth row, which should contain five random numbers in the range 9-10.

I've attached my program what I've worked out.

One fairly straightforward approach

To create a range of random numbers, it is rand*(max-min)+min.  Make a subVI that does this calculation.  All you have to do then is put this new subVI into 2 FOR loop, autoindex out, and you have a 2D array.

yes, I've done this part.  I've included the VI in my post.

I want the first row in the 2D array to range random numbers from 0 to 1

the second row to range random numbers from 1 to 2

the third row to range random numbers from 2 to 3

the fourth row to range random numbers from 3 to 4

the fifth row to range random numbers from 4 to 5

the sixth row to range random numbers from 5 to 6

the seventh row to range random numbers from 6 to 7

the eighth row to range random numbers from 7 to 8

the ninth row to range random numbers from 8 to 9

and lastly, the tenth row to range random numbers from 9 to 10

I'm not getting you...shouldn't there be iniial value for max and min to do the sub-vi

Take another look at the snipett I posted earlier

[Shalins]

I tried your idea and this is what I have 🙂

[JÞB]

Try that again

Withou the odd display formating

where do I get the array from on the block diagram like in the pic you posted.

After running the VI, he right-clicked on the output wire and selected "create constant".
