Ques 21. How does `scipy.io` module support input and output operations?
The `scipy.io` module provides functions for reading and writing data in various formats, including MATLAB files, NetCDF, and WAV files. It is used for input and output operations in scientific computing.
Ques 22. What is the purpose of `scipy.fftpack` module?
The `scipy.fftpack` module provides functions for fast Fourier transforms (FFT). It is used for efficient computation of discrete Fourier transforms and related operations.
Ques 23. Explain the use of `scipy.optimize.least_squares`.
`scipy.optimize.least_squares` is used for solving nonlinear least squares problems. It minimizes the sum of squared differences between observed and predicted values.
Ques 24. How can you perform sparse matrix factorization using `scipy.sparse.linalg.svds`?
`scipy.sparse.linalg.svds` is used for sparse matrix factorization using the singular value decomposition (SVD) method. It is efficient for large, sparse matrices.
Ques 25. Explain the purpose of `scipy.stats.multivariate_normal`.
`scipy.stats.multivariate_normal` represents a multivariate normal (Gaussian) random variable. It can be used to generate random samples and evaluate the probability density function.
