Nonetheless, both single and multistep methods have been very successful and there are very reliable matlab routines and libraries for other languages available to solve odes using both types of methods. Multistep methods require information from several preceding steps in order to find and are a little more difficult to use. All arrays must be the same size, or any of them can be scalar. In this case the first input to randi describes the range of possible values for the integers, and the second two inputs describe the number of rows and columns.
