344 A special case of broadcasting that may be familiar is when all 347 A special case of broadcasting that may be familiar is when all
345 dimensions of the array being broadcast are 1, i.e. the array is a 348 dimensions of the array being broadcast are 1, i.e., the array is a
346 scalar. Thus for example, operations like @code{x - 42} and @code{max 349 scalar. Thus for example, operations like @code{x - 42} and @code{max
347 (x, 2)} are basic examples of broadcasting. 350 (x, 2)} are basic examples of broadcasting.
