A 2D array has rows and columns. This one has 3 rows and 4 columns. We say it is a “3-by-4” array (a.k.a matrix) 12 17 49 61 38 18 82 77 83 53 12 10 Can have a 2d array of strings or objects. But we will just deal with 2d arrays of numbers.

number (element) in an array: y = sin (x) This is an e cient way to do calculations in Python, but sometimes we need to do something more complicated on each element separately. The main reason is if elements in the array depend on each other. If we do an array operation then each number in the array is treated separately.

NumPy Fundamentals • Why Numpy? • Remember that Python does not limit lists to just elements of a single class • If we have a large list and we want to add a number to all of the elements, then Python will asks for each element: • What is the type of the element • Does the type support the + operation • Look up the code for the + and execute • This is slow

18 Lab 2. NumPy and SciPy Arrays Conceptually, a 1-dimensional array (called a 1-D array) is just a list of numbers. An n-dimensional array (or n-D array) is an array of (n 1)-dimensional arrays. Thus, any 2-D array is conceptually a matrix, and a 3-D array is a list of …
