Book claims that matrix multiplications require using a function #163

Closed Hofer-Julian closed 2 years ago

Hofer-Julian commented 2 years ago

The book claims here:

Multiplying two two-dimensional arrays with * is an element-wise product, while matrix multiplications require using a function.

Just to later introduce the @ operator. I assume that is a remnant of former editions of the book.
