"Vectorized" Natural Recordings by Native Speakers
Vectorized
In computing, a vectorized operation or operation is one that operates on numerical arrays, in contrast to operations that operate on scalars, one element at a time. These vectorized operations are performed across the entire array simultaneously, making them more efficient and faster for operating on large datasets.
In other words, a vectorized operation allows you to perform a single operation on multiple elements of an array in a single command, as opposed to using a loop to operate on each element individually.
Examples of vectorized operations include:
Adding or multiplying two arrays element-wise
Computing the mean, median, or standard deviation of an array
Performing linear algebra operations, such as matrix multiplication
Vectorization is an essential feature in many programming languages, including NumPy in Python and MATLAB. It simplifies numerical computations and makes it possible to perform complex analysis on large datasets with high performance and efficiency.
Example in Python:
python
import numpy as np
