Vectors, matrices, and arrays of higher dimensions are essential tools in numerical computing. When a computation must be repeated for a set of input values, it is natural and advantageous to represent the data as arrays and the computation in terms of array operations. Computations that are formulated this way are said to be vectorized.1 Vectorized computing eliminates the need for many explicit loops over the array elements by applying batch operations on the array data. The result ...
