Hey there, I know, this question is quite for beginners/stupid. But I'm stuck to a certain problem for my FROG LabVIEW program. Found nothing specific by google and in here... The program is state machine based. The certain states will initialize variables, calculate the scanning parameters, control the scan process and collect the necessary position data. The attached screenshot is showing the scanning and position aquiring process. The axis will go to a certain position and will then move the defined scanrange in small steps. For each step, the programm will compare the desired position to the actual position, returned by the motion controller. Is the position within a range, the axis will move the next step. This is repeaded "number of steps" times. This number is depending on expected pulselength and stepsize. Now my problem: I want to fill an array, where the row/index is equal to the current step number. At the moment, the array should have three columns, and of course as many rows as steps. Column one should be filled with the index/step number, the other to with the desired and actual position. Since I'm using a state machine, I'm obviously within a while loop. I know, that, in general, such an array can be build, by having the data collecting process inside a loop and the array outside. With a shift register, the data will be auto indexed by the iteration i. But, afaik, it's better to avoid loops in a loop. So, how to initialize a "num of steps" x 3 array inside a loop, without using an additional loop with shift registers? The screenshots show my current "solution". In the state, where the scanning parameters are calculated, I initialize my array. It is filled with data in the scan state. Is this "correct" or are there any other solutions? Doesn't seem to be a good solution atm... Hopefully the attached code is enough. Just need to know the basic principle of initialize and fill this array with data 🙂

Hi Johannes, Then, each field should be filled with the desired values by overwriting each 0/NaN. Then why did you use InsertIntoArray instead of ReplaceArraySubset?

Fill array INSIDE loop/state machine (beginners question...)

Solved!

I would probably use the "in place element" structure to modify a cluster element.

It is not clear to me that you even need a cluster. Why not just have the 2D array in the shift register?

back from holidays...

I might need to add more stuff or data arrays 😉

Thank you all again!
