Preconditioner Condition Improvement Factor: Calculate condition improvement factor from original condition number and preconditioned condition number.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Preconditioner Condition Improvement Factor to answer this question: calculate condition improvement factor from original condition number and preconditioned condition number? Enter original condition number and preconditioned condition number; the calculator shows condition improvement factor. For example: original condition number=1200 and preconditioned condition number=24 produce condition improvement factor=50. The answer tells you condition improvement factor.
Age 15Explain it to a 15-year-oldConnect it to the formula
Condition improvement factor compares the original condition number with the preconditioned one. This page evaluates the relationship directly. The rule is c=a/b. Its input values are original condition number, preconditioned condition number, and the main result is condition improvement factor. For example: original condition number=1200 and preconditioned condition number=24 produce condition improvement factor=50.
CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated preconditioner condition improvement factor relation over the valid real-number domain stated below. The implemented relation is c=a/b, evaluated from original condition number, preconditioned condition number to produce condition improvement factor. Condition improvement factor compares the original condition number with the preconditioned one. This page evaluates the relationship directly. Use the same norm and operator formulation for both condition numbers.
Inputs and valid domain
- original condition number must be a finite real number.
- preconditioned condition number must be a finite real number.
Important boundary: Use the same norm and operator formulation for both condition numbers.
The formula
c=a/b
How the calculator works through it
It substitutes original condition number, preconditioned condition number into the formula and exposes every numerical step above. The main output is condition improvement factor.
Read the result correctly
The condition improvement factor is the direct answer to “calculate condition improvement factor from original condition number and preconditioned condition number.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
A worked check
original condition number=1200 and preconditioned condition number=24 produce condition improvement factor=50.
Where this model stops being reliable
Use the same norm and operator formulation for both condition numbers.
Learn it by changing one value
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
