Multi-dimensional arrays So far we’ve just used one-dimensional arrays, i.e. arrays with just one index x[ i ] Often we will want to handle arrays which depend on more than one dimension This is not much more complicated in Python than one-dimensional arrays, and the same ideas apply to both Dr Ben Dudson Introduction to Programming - Lab 3 ...

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- …
