The np.linspace function in Python’s NumPy library is a powerful tool for generating evenly spaced numbers over a defined interval. It is widely used in numerical computing, simulations, and plotting to create smooth transitions between values. By specifying start, stop, and the number of samples, np.linspace returns a precise array ideal for graphs or mathematical models. This function is essential for creating datasets where equal spacing between points matters, such as plotting sine waves, probability curves, or interpolation. Explore the np.linspace guide to understand its parameters, examples, and advanced applications that simplify complex array generation in Python programming.
