    Study Notes

    Sources of Errors in Numerical Analysis

    • Errors in numerical analysis can arise from round-off errors, truncation errors, and modeling errors
    • Round-off errors occur due to the finite precision of computer arithmetic
    • Truncation errors result from approximating an infinite process by a finite one
    • Modeling errors arise from simplifying assumptions and simplifications in the mathematical model

    Input Information in Numerical Analysis

    • Input information in numerical analysis is rarely exact due to measurement errors, data uncertainty, and model uncertainty

    Infinite Algorithms in Numerical Analysis

    • Infinite algorithms are not practical for numerical analysis as they would require an infinite amount of time and infinite precision

    Error Accumulation in Numerical Analysis

    • Errors can accumulate in computational errors due to the compounding effect of small individual errors
    • This can lead to unreliable results and loss of accuracy

    Goal of Numerical Analysis with Regards to Errors

    • The main goal is to minimize errors and maximize accuracy through careful analysis and choice of algorithms
    • This involves balancing Trade-offs between accuracy, speed, and computational resources
