Multiple Array

[altenbach]

Here is one possibility to calculate the sum of the 4 element subset (array subset) starting with row index 3, multiplied by the max/min controls and taking the sum.

There are many other ways to do this, of course. (you can even omit one of the sums, but it'll costs more memory).

Thank you very much for the advice sir, I will try to learn more about the Vi program to solve my case

[Array01]

I want to make array multiplication in LabVIEW like the source code below but I'm confused to make it in VI forms can anyone help me?

Datarealtime = [1.751933    0.600301    -0.532437   -0.399414];

Bias = -6.6169046946979;

for i = 1:length(DataArifS5)

    Jmlh(i) = DataArifS5(i,1)*DatatrainingS5(i,2)*((Datatraining(i,3)*Datarealtime(1,1))+(Datatraining(i,4)*Datarealtime(1,2))+(Datatraining(i,5)*Datarealtime(1,3))+ (Datatraining(i,6)*Datarealtime(1,4)));

end

jumlah = sum(Jmlh)

hasil = jumlah+Bias

Just start with my example.

• One thing you need to know is that array indices start with zero in LabVIEW, so the first element has index=0, not 1.
• If you autoindex a 2D array at a FOR loop boundary, you'll get one row (1D array) at a time inside the loop. You should not wire N, because the number of rows will automatically determine that when autoindexing.
• Your datarealtime array is 1D, not sure why you think you need two indices. As I demonstrated in my example, if you don't autoindex, the 1D array, you get it inside the loop unchanged and multiplying with the correct row subset will do the multiplication elementwise.
• ...

I recommend you start with the learning resources listed at the top of the forum.

Thanks for the response and suggestion sir
sorry, I want to ask about the for loop in Labview, can it be used as a counter of the array index to move the first line to the second line? as in other programs such as python, C++ and others.

I have no idea what you mean by that!

Indexing is zero based, so you can do simple math to convert your index into a LabVIEW index. (This comes to mind). When autoindexing, you don't even need to worry about indices, because you get one row at a time in the correct order.

This is called "Autoindexing" - and is a very basic feature in LabVIEW.

Did you start with all those Training resources offered at the top of the LabVIEW board? I guess you already got a recommendation to tackle them!
