1: How do I create a random valued array in NumPy? You can use the NumPy function "random" to create a random valued array. For example, "np.random.rand(3, 4)" will create a 3x4 array of random values. 2: How do I set the seed for a random valued array in NumPy? Use the ...

19. Sub-matrix Strides in Reshaped Array Write a NumPy program that creates a 1D array of 20 elements and use reshape() to create a (4, 5) matrix. Slice a (2, 3) sub-matrix and print its strides. Sample Solution: Python Code: ...
Currently, array creation by default returns pointers that are aligned to the boundary of the largest data type for the platform. Some CPUs have SIMD instructions for data loads/stores that work faster with data pointers aligned to higher boundaries, like 64 bytes instead of 8. NumPy arrays are...
