How to take sum from middle iteration to last iteration?

[Abul]

I want to  6 linear differential equations that why i used the simulation method, probably using mathematic palette will be diffucult task. Thanks

I want to simulate 6 linear differential equations that is why i used simulation loop, probably using mathematic palette will some how be difficult. Thanks

Hi Abul,

Yes, using the Mathematics section of the Functions palette will probably require a little more coding on your end, but you will be able to synchronize your program like you want. I have attached an example here that shows how to solve a simple linear ODE. Hopefully this will help you get started.

I am grateful for all your assistance. I have already synchronized the two loops, using the simulation parameter. I am now only interested in finding the size of the array. I am having 12 rows and 6 columns, pls, what is the size of this array?

[LandBelenky]

The size of the array is 12x6.

As I understand, you want to take the sum of elements [6,0]+[7,0]+[8,0]+[9,0]+[10,0]+[11,0].... and then a separate sum for [6,0]+...[6,11].... and a separate sume for [7,0]+...[7,11].

Can you post your most recent version?

[Abul]

Exactly that is sum the i want to take, attached is the vi. you can stop it when it call iteration the last iteration. Pls, there is also an alternative of stopping the while loop after it call last iteration, would be appreciated. Thanks

Hi Abul,

By adding a count to your iteration and an OR function, you can stop the VI after it reaches a certain interation or when you hit the Stop button. I have attached a picture of what I am talking about. Hope that helps!

Thanks so much. What of finding the size of the array? so that i can take the sum of each variable separately from middle iteration to the last iteration?

Hi Abul,

There is actually a VI called Array Size that will return the size of the array. It can be found on the Functions Palette under Programming->Array->Array Size. It will be the first option. Hope this helps!
