Double Pointer and 2D Array • The information on the array "width" (n) is lost. • A possible way to make a double pointer work with a 2D array notation: o use an auxiliary array of pointers, o each of them points to a row of the original matrix. int A[m][n], *ptr1, **ptr2; ptr2 = &ptr1; ptr1 = (int *)A; WRONG

Python code to find 2D array size
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.

2D arrays • So far, we have been working with one dimensional arrays (e.g. array([1,2,3,4,5,…]) • With “matching” 1D arrays for x and y we can plot 2D data- such as position vs time. Each “data point” contains two pieces of information: x, and y (or time and position). • A 2D array allows us to plot 3D data points- …
