MATLAB is used in a lot of different ways by lots of people in occupations you might not necessarily think about when it comes to a math product. In fact, math is used in ways that many people don’t consider.
Many engineering disciplines rely on various kinds of math to ensure that the results of any design process or new theory of how the universe works actually make sense. A new building isn’t much use if it can’t hold up to the stresses placed on it.
It may be hard to believe, but linear algebra really is part of the workplace. For example, to calculate Return on Investment (ROI), you must know algebra. The same holds true for the following:
Numerical analysis relies on approximation rather than the precision you see in symbolic math. Performing certain building construction tasks is impossible without applying numerical analysis, and astronomy seems to require heavy use of it as well. You probably won’t see a carpenter applying numerical analysis, but you will see architects who might need to do so.
Some people simply enjoy playing with math. It’s the reason that so many theorems are available today to solve problems. These people are engaged with math in a way that few others can readily understand. MATLAB makes it possible to play with math, to create new ways of using numbers to perform useful tasks.
Image processing is the act of managing the pixels in an image using math techniques to modify the matrix values. Techniques such as adding two matrices together are common when performing image processing.
