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
