As of the last update in April 2023, thenumpy.uniquefunction in Python does not provide a built-in option to return the unique elements without sorting them. However, we can achieve a non-sorted unique list by using a combination of other NumPy functions and Python constructs. import numpy ...
Mimic `np.select(condlist, choicelist)`. Notice it assumes that all `arrays` are of the same shape, or can be broadcasted together. All functions in `choicelist` must accept array arguments in the order given in `arrays` and must return an array of the same shape as broadcasted `arrays...
Case 7: np linspace 2D array in Python Althoughnumpy.linspaceinherently generates a 1D array in Python, we can easily reshape it to 2D or use it in combination with other functions to create 2D arrays in Python. import numpy as np two_d_array = np.linspace(0, 1, num=20).reshape(4,...

Universal Functions (ufuncts) Implement vectorization (operations applied to whole arrays instead of individual elements) in NumPy which is way faster than iterating over elements. Also provide broadcasting (when smaller array is cast across the larger array so that they have compatible...
