Use input() with the 's' option.

It is not possible to tell mathematical formulae apart from random characters. There is no standard for mathematical formulae. What looks like garbage to a chemist might make complete sense to a particle physicist, and a particle physicist might be lost with some of the the computing theory notation.

Yes.

The majority of the class is focused on workflows etc. and not on math or anything very specific. You will see some functions for doing linear algebra (which you may or may not find useful) as well as many others. That's one of the best parts about MATLAB: you can use the linear algebra functionality, when necessary, without really needing to know how it works under the hood.

str2num() will do that calculation.

str2num() works by using eval() on whatever string is passed in. So if the user put

delete('*')

into the field, and you used str2num() on it, then all of your files in the current directory wold get deleted.
