Web(c) Write a program to use solve in numpy.linalg to solve the values of the V i when there are N = 5, 6 internal junctions with unknown voltages. (d) Now solve V i for the case where there are N = 10000 internal junctions. Use the solve function in numpy.linalg and also the banded function. Compare these two method by the calculation time. WebFunctional Differences between NumPy vs SciPy. 1. SciPy builds on NumPy. All the numerical code resides in SciPy. The SciPy module consists of all the NumPy functions. It is however better to use the fast processing NumPy. 2. NumPy has a faster processing speed than other python libraries. NumPy is generally for performing basic operations like ...
