Creative Creek was founded in 1999 by Dr. Clay M. Thompson to develop and market the MathU calculator for Palm OS. Since then, Creative Creek and Dr. Thompson have created a series of professional calculators for mobile devices like the iPhone, Palm and Windows Mobile. Creative Creek has also created several custom applications for their clients.

The calculators are sold via the Apple AppStore.

The consulting and custom development division of Creative Creek was moved to Mathematical Engineering (mathengineering.com) in 2009. Mathematical Engineering specializes in MATLAB consulting as well as custom software development for iPhone, MATLAB and Python. Dr. Thompson is active with both divisions.

Clay M. Thompson has been doing software development since 1984. Trained as engineer, he has frequently found it necessary to create the tools needed to solve his engineering problems.

“Programming has always been a passion for me even though it has not always been my main job”, said Thompson in a recent interview. “My love for programming was first discovered when I received a HP-67 programmable calculator while in high school. MathU Pro is in many ways modeled after that calculator and the other Hewlett-Packard calculators I have enjoyed over the years.” An especially conscientious developer, Thompson does extensive testing of his applications before releasing them. He is constantly striving to improve his products. Creating well crafted products is Thompson’s passion.


Before founding Creative Creek, LLC, Thompson worked at The MathWorks, Inc. where he authored the Control Toolbox 3.0 upgrade, Image Processing Toolbox 1.0, and oversaw the MATLAB language as the chief language designer for MATLAB 5.0. “I learned a lot about numerical programming while at The MathWorks.”

Thompson now develops full time. He splits his time between creating new products, adding new features and software consulting. Two of his products MathU RPN and MathU 12D are calculators for iPhones.
