# Matt Tearle

### MathWorks

I love MATLAB. I love teaching people to love MATLAB.

I love it so much that I went to work for the people who make MATLAB. I spend my days at MathWorks creating material to help people learn MATLAB. Life is good.

(My love of teaching MATLAB notwithstanding, please don't email me for help -- post a question to MATLAB Answers instead. Firstly, your email will probably be swallowed by my spam filter. Secondly, private consulting isn't in my job description.)
