To return the lower triangle of an array, use the numpy.tril() method in Python Numpy −The 1st parameter is the input arrayThe 2nd parameter is the 'k' i.e. the diagonal above which to zero elements.k = 0 (the default) is the main diagonal, k 0 is above.The function returns a copy of an array with elements above the k-th diagonal zeroed. For arrays with ndim exceeding 2, tril will apply to the final two axes.StepsAt first, import the required library −import numpy as npCreate a 2d array −arr = np.array([[36, 36, 78, 88], [92, 81, 98, 45], [22, 67, ...

To create an array with ones at and below the given diagonal and zeros elsewhere, use the numpy.tri() method in Python NumpyThe 1st parameter is the number of rows in the arrayThe 2nd parameter is the number of columns in the arrayThe "type" parameter is used to set the type of the returned arrayThe tri() function returns an array with its lower triangle filled with ones and zero elsewhere; in other words T[i,j] == 1 for j

To create a two-dimensional array with the flattened input as a diagonal, use the numpy.diagflat() method in Python Numpy. The 'K parameter is used to set the diagonal; 0, the default, corresponds to the “main” diagonal, a negative k giving the number of the diagonal below the main.The first parameter is the input data, which is flattened and set as the k-th 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, ...

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
