Both inputs should be u-by-m-by-n numeric arrays, with each row representing a Cartesian vector and each element representing a component of that vector. Normal vectors are 3x1x1, but this function allows vectors with a different number of components, and it allows the user to input multiple vectors as an array with multiple rows. Returns double if any input is double; float otherwise When dot() is entered without any arguments, it prints its description, as shown below.
