Breaking a matrix into chunks

[mecheng86]

Hello.

I was wondering, what would be the best way to break a large column array into pieces of a specific size?

It depends on what you want to do later with them. But generally, Index Array and Array Subsets are your friends.

p.s. What is column array?

[mecheng86]

A column array is simply a 1D array in the form of a column.

[ghighuphu]

A 1D-array has no vertical or column form. It is a visual layout chosen by the user on the front panel.

This information does not change the statement and the hidden question in Message 2.

Do you want to break it into regular pieces of equal size/length? Is the length of a smaller piece a divisor of the total length of the large array?

[mecheng86]

Yes and not necessarily. I'm working on a program responsible for collecting data from a 6-degree loadcell. I want to be able to take all data observed and multiply it by a 6x6 matrix to change the incoming voltage to newtons and newton-meters. If it helps, I've attached the program below.

Can you replace your VoltageIn express VI with a 2D DBL array diagram constant containing typical data?

(index array is resizeable, use a parallel FOR loop instead of all these individual AxB instances, etc.)

I've modified the program and attached it below.

Your array control does not contain any data. Make the current values the default before saving.

(You also seem to be confused about indexing. The first element is index 0 in LabVIEW.)

Sorry about that. The default values should now be set.
