Design your own galaxy ! :-)

For pedagogic / scientific diffusion purposes. Is not a rigorous astrophysical model.

F5 in galaxy_model.m or galaxy_model; in console to run the program and plot the figure.

A lot of parameters -curvature, number of arms, number of stars and many others- are available in the file header to tune the shape of the model.

Since these parameters are quite sensitive, my advice is to first test them individually -one by one- to understand their influence.

For some out of range parameter values, you may encounter this warning in Matlab console :

> Warning: Using only the real component of complex data.
> In getRealData (line 52)
> In scatter3 (line 59)
> In spiral_galaxy_model (line 115)

In this kind of case, just go back to some reference example parameter set, and do again your parameter tuning, one by one.
