Fitting an array

Share icon

Hi everyone,

I have an array of points that I am plotting to get a 2D Gaussian. What I want to do is fit this data to a 2D Gaussian using Igor's fit functions but I am not sure how I can turn this array into x and y waves to fit the data. Any help or insight would be greatly appreciated. I have attached a sample .pxp file of the data with the corresponding 3D plot.

Cheers,
