ufunc Differences

NumPy's diff ufunc calculates the difference between consecutive elements in an array. This is useful for analyzing changes or trends in datasets.

Key Topics

Basic Differences

The diff function computes the difference between consecutive elements along a specified axis.

Example

# Differences in array
import numpy as np

arr = np.array([10, 20, 30, 40, 50])

differences = np.diff(arr)

print("Differences between consecutive elements:", differences)

Output

Differences between consecutive elements: [10 10 10 10]

Explanation: The diff ufunc computes the difference between consecutive elements, revealing trends or changes in the data.

Key Takeaways

  • Difference Computation: Use diff to calculate changes between consecutive elements.
  • Applications: Analyze trends, compute rate of change, or detect anomalies in data.
  • Efficiency: Operates element-wise, ensuring fast computations on large datasets.
