I have an array of size 600 by 600 pixels. In a circle of given radius (say 50 pixels) and given origin (given ith row and jth column), I want to plot gaussian distribution, i.e., give the pixels the value of a 2-D gaussian distribution with peak at the origin. How do I do this in labview ? Thanks.

You would run your x and y values through the 2D Gaussian function but making the origin 300,300 (for your given 600x600 pixel array). Here's what I get on an intensity chart given an amplitude of 10 and sigma = 100 pixels: Here's the example (quick and dirty) code:

Build/ assign value to array elements

Solved!

Sorry for resuming this old post, but I don't understand the division by 20000 in the example. Why do you do that and how did you choose the value?

Thanks 🙂
