Keyboard Mathematical Functions
You can use these mathematical functions in expressions with real or complex values. You
can use some of them with lists, vectors, matrices, or strings.
When you use lists, vectors, or matrices, the valid functions return a list of results calculated
on an element-by-element basis. If you use two lists, vectors, or matrices in the same
expression, they must be equal in dimension.
