To create a two-dimensional array with the flattened input as a diagonal, use the numpy.diagflat() method in Python Numpy. The first parameter is the input data, which is flattened and set as the kth diagonal of the output. The second parameter is the diagonal to set; 0, the default, corresponds to the “main” diagonal, a positive (negative) k giving the number of the diagonal above (below) the main.NumPy offers comprehensive mathematical functions, random number generators, linear algebra routines, Fourier transforms, and more. It supports a wide range of hardware and computing platforms, and plays well with distributed, GPU, and sparse ... Read More

To return evenly spaced numbers on a geometric progression, use the numpy.geomspace() method in Python Numpy −The 1st parameter is the "start" i.e. the start of the sequenceThe 2nd parameter is the "end" i.e. the end of the sequenceThe 3rd parameter is the num i.e. the number of samples to generate. Default is 50.We have set complex inputs.The start is the starting value of the sequence. The stop if the final value of the sequence, unless endpoint is False. In that case, num + 1 values are spaced over the interval in log-space, of which all but the last (a ... Read More

To return evenly spaced numbers on a log scale, use the numpy.logspace() method in Python Numpy. The 1st parameter is the "start" i.e. the start of the sequence. The 2nd parameter is the "end" i.e. the end of the sequence. The 3rd parameter is the "num" i.e. the number of samples to generate. Default is 50. The 4th parameter is the "base" i.e. the base of the log space. The step size between the elements in ln(samples) / ln(base) (or log_base(samples)) is uniform.In linear space, the sequence starts at base ** start (base to the power of start) and ends ...

The numpy.matrix method is used to interpret a given input as a matrix. It returns a matrix from an array-like object. Its syntax is as follows −numpy.matrix(data, dtype=None, copy=bool)where, data - It is the input data.dtype - It represents the data type of the output matrix.copy - If the input data is already an ndarray, then this flag copy determines whether the data is to be copied (default behavior), or whether a view is to be constructed.Example 1Let us consider the following example −# import numpy library import numpy as np # matrix function y = np.matrix([[4, 5], [7, ...
