08 Jun 2012 (Updated )

Fits a 2D Gaussian function to simulated data.

File Information

The program generates a 2D Gaussian. The program then attempts to fit the data using the MatLab function “lsqcurvefit “ to find the position, orientation and width of the two-dimensional Gaussian.
Execute “mainD2GaussFitRot.m” with not input parameters.
The two-dimensional Gaussian function is defined by the function “D2GaussFunctionRot.m” and “D2GaussFunction.m”

Required Products MATLAB
MATLAB release MATLAB 7.12 (R2011a)

What a pity that this is a script, which generates the data by a random function. Before it can be used for real problems, substantial changes are required.

It would increase the usability, if the calculations are move to a function and separated from the generation of test data.

Works well for 2D system...any chance of broadening it to 3D?

file was renamed and the definition of the gaussian width was changed.
Also a screenshot was added.
