    Study Notes

    Numerical Integration

    • Definition: Numerical integration is a technique used to approximate the value of a definite integral.
    • Types of Numerical Integration:
      • Rectangular Rule: Approximates the area under a curve by dividing it into rectangles and summing their areas.
      • Trapezoidal Rule: Approximates the area under a curve by dividing it into trapezoids and summing their areas.
      • Simpson's Rule: Approximates the area under a curve by dividing it into parabolic segments and summing their areas.
    • Python Libraries for Numerical Integration:
      • scipy.integrate: Provides functions for numerical integration, including quad and romberg.
      • mpmath.quad: Provides arbitrary-precision numerical integration.

    Algorithm Efficiency

    • Big O Notation: A measure of an algorithm's computational complexity, expressed as a function of the input size.
    • Time Complexity: Measures the time taken by an algorithm to complete.
    • Space Complexity: Measures the memory used by an algorithm.
    • Optimizing Algorithm Efficiency:
      • Vectorization: Use NumPy's vectorized operations to reduce loop iterations.
      • Parallelization: Use parallel processing to distribute computations across multiple cores.
      • Caching: Store intermediate results to avoid redundant computations.

    Scientific Computing

    • Definition: Scientific computing involves using numerical methods and algorithms to solve scientific problems.
    • Key Concepts:
      • Numerical Analysis: The study of numerical methods for solving mathematical problems.
      • Computational Science: The use of computational methods to solve scientific problems.
