  1. I have an array of classes, let's call the object TestPass, of size 1 (but it is an array because it can scale out to multiple test passes). In this class, there is one other nested class which is not too complex, then various numeric and string fields to hold some private data. There is also an array of clusters. In this cluster there is a string, two XY pair clusters, and an integer. Not very confusing. This array of clusters gets fairly large, however, upwards of 80-100k elements. What I am finding is when I index the array of pass classes it is crazy slow. On the order of 30 ms. Doesn
  2. Hi All, I have 3 analogue and 2 digital waveforms that I want to repeat multiple times with a delay between them. I could do this programmatically using a while loop during their playback but ideally I'd like to create a waveform as a delay and concatenate them all so that the resultant waveform is the what will be sent. My current solution is to have a pair of for loops inside a larger for loop. The sub for loops concatenate the waveforms with the shift registered waveforms and then with a waveform of my choosing (the delay waveform). Attached is a snippet of code. However, to produce a w
  3. I am writing a performance-sensitive application which requires the use of a nearest-neighbor lookup. Originally I used a brute-force method, but unfortunately this gets to be very slow as the data size increases . I have a point cloud of ~100k points in 2D, and need around 50k nearest neighbor lookups per second as a minimum performance requirement. As a solution I wrote a kd-tree in .Net and used LabView to call the .Net dll. However, I discovered that each .Net transaction carries with it about a 0.5ms delay. I've tried bunching the data up into groups, but this only helps so much, as I am
