Transposing And Reshaping A Matrix
Transposing And Reshaping A Matrix Table Of Contents: arr.reshape(), arr.transpose(), arr.T (1) arr.reshape() Syntax: numpy.reshape(a, newshape, order=’C’) Parameters: a:array_like – Array to be reshaped. newshape: int or tuple of ints – The new shape should be compatible with the original shape. If an integer, then the result will be a 1-D array of that length. One shape dimension can be -1. In this case, the value is inferred from the length of the array and remaining dimensions. order{‘C’, ‘F’, ‘A’}, optional – Read the elements of a using this index order, and place the elements into the reshaped array using this index

How To Get Unique Items And Counts In Numpy ?
How To Get Unique Items And Counts In Numpy ? Table Of Contents: np.unique() Examples Of ‘np.unique( )’ (1) np.unique() Returns the sorted unique elements of an array. You can also get the unique element counts. Syntax: numpy.unique(ar, return_index=False, return_inverse=False, return_counts=False, axis=None, *, equal_nan=True) Parameters: ar: array_like – Input array. Unless axis is specified, this will be flattened if it is not already 1-D. return_index: bool, optional – If True, also return the indices of ar (along the specified axis, if provided, or in the flattened array) that result in the unique array. return_inverse: bool, optional – If True, also return the indices of

How To Generate Random Numbers Using NumPy ?
How To Generate Random Numbers Using NumPy ? Table Of Contents: What Are Random Numbers? Examples Of Random Number Generators. (1) What Are Random Numbers? As the name suggests, a random number is a number chosen by chance – i.e., randomly, from a set of numbers. All the numbers in a specified distribution have an equal probability of being chosen randomly. (2) Random Numbers? Syntax: Default Random Number Generators np.random.default_rng() Example: Initializing The Generator rng = np.random.default_rng() Using ‘random()’ Function To Generate Numbers Syntax: numpy.random.random(size=None) Parameters: size : int or tuple of ints, optional – Output shape. If the given shape is,
