In Python, NumPy is a powerful library for numerical computing, including support for logarithmic operations. The numpy.log() function is used to compute the natural logarithm element-wise on a NumPy array. To compute the natural logarithm of x where x, such that all the elements of the give...

To add a simple linear trendline to your Matplotlib plot, you can use NumPy for linear regression. Here’s how you can do it: importnumpyasnpimportmatplotlib.pyplotasplt# Sample datax=np.array([1,2,3,4,5])y=np.array([2,3,5,7,11])# Create a scatter plotplt.scatter(x,y)# Calc...
plot_figure(x, y) # Calling the main() function if __name__ == "__main__": main() Output: Figure 1 [adinserter block=”3″] Explanation: First, we imported the libraries required to run the code. We imported the Numpy andmatplotlib.pyplotusing the import statement of python. ...

With NumPy, you can use arange() to create an array with specific start, stop, and step values. However, arange() has one big difference from MATLAB, which is that the stop value is not included in the resulting array. The reason for this is so that the size of the array is equal...
