 Eigen also provides typedefs for some common cases, in a way that is similar to the Matrix typedefs
 but with some slight differences, as the word "array" is used for both 1-dimensional and 2-dimensional arrays.

+We adopt the convention that typedefs of the form ArrayNt stand for 1-dimensional arrays, where N and t are

 First of all, of course you can multiply an array by a scalar, this works in the same way as matrices. Where arrays
 are fundamentally different from matrices, is when you multiply two together. Matrices interpret
