Dear Sir,
Yes, I want to generate the data by two Gaussian but mean from one of them generatated from polar its coordinates. I am confused about the algorithm? I know how to generate two Gaussian data with certain mean&covariance matrix using mvnorm but what about mean from its polar coordinates?
Thanks for your help.

Best wishes,

It is not clear what you want.  Do you need to generate the data or do something with existing data?
