To compute the bit-wise NOT of a 2D array element-wise, use the numpy.bitwise_not() method in Python Numpy.Computes the bit-wise NOT of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator ˜.The where parameter is the condition broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the default out=None, locations within it where the condition is False will remain uninitialized.StepsAt first, import ... Read More
To Interpret the input as a matrix, use the numpy.asmatrix() method in Python Numpy. The dtype parameter is used to set the type of the output array. Unlike matrix, asmatrix does not make a copy if the input is already a matrix or an ndarray. Equivalent to matrix(data, copy=False).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 array libraries.StepsAt first, import the required library −import numpy as npCreate a 2d array −arr = np.array([[36, 36, 78, ...

To compute the bit-wise NOT of an array with signed integer type, use the numpy.bitwise_not() method in Python Numpy. Computes the bit-wise NOT of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator ˜.The where parameter is the condition broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result.

To unpack elements of a uint8 array into a binary-valued output array, use the numpy.unpackbits() method in Python Numpy. The result is binary-valued (0 or 1). The axis is the dimension over which bit-unpacking is done. The axis is set using the "axis" parameter.Each element of the input array represents a bit-field that should be unpacked into a binary-valued output array. The shape of the output array is either 1-D (if axis is None) or the same shape as the input array with unpacking done along the axis specified.The axis is the dimension over which bit-unpacking is done. None implies ... Read More
To return the upper triangle of an array, use the numpy.triu() 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.Here, k = 0 (the default) is the main diagonal, k < 0 is below it and k > 0 is above.' Array. The k = 2 value is to zero elements just above the main diagonal.The function returns a copy of an array with the elements below the k-th diagonal zeroed. For arrays with ndim exceeding 2, triu will apply to the final two axes.StepsAt ... Read More

To create a record array from a (flat) list of array, use the numpy.core.records.fromarrays() method in Python Numpy. It returns the record array consisting of given arrayList columns.The first parameter is a List of array-like objects (such as lists, tuples, and ndarrays). The dtype is the valid dtype for all arrays. The formats, names, titles, aligned, byteorder parameters, if dtype is None, these arguments are passed to numpy.format_parser to construct a dtype.StepsAt first, import the required library −import numpy as npCreate a new array using the numpy.array() method −arr1 = np.array([[5, 10, 15], [20, 25, 30]]) arr2 = np.array([[9, 18, ...
