I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

comment How to use the function ImageCorrelate?
This question appears to be off-topic because it is not really about Mathematica, but concerns certain mathematical or physical concepts that must be mastered to properly use the Mathematica built-in functions mentioned in the question.

On OS X, [Return] inserts a newline and [Enter], which is different key, produces evaluation.
