Relative Tolerance Matlab
is a measure of the error relative to the size of each solution component. Roughly, it controls the number of correct digits in all solution components, except those smaller than thresholds AbsTol(i). The default, 1e-3, corresponds to 0.1% accuracy. AbsTol — AbsTol(i) is a threshold below which the value of the ith solution component is unimportant. The absolute error tolerances determine the accuracy when the solution approaches zero. I do not understand why AbsTol determines the accuracy when the solution approaches zero (indeed, if the solution of my problem is a circular orbit of 7000 km radius this does not meet) and why RelTol controls the number of correct digits in all solution components, except those smaller than thresholds AbsTol(i). I would like to have simpler and understandable definitions. 0 Comments Show all comments Tags No tags are associated with this question. Products No products are associated with this question.

Translate Selecting Absolute Tolerance and Relative Tolerance for SimulationSimBiology uses AbsoluteTolerance and RelativeTolerance to control the accuracy of integration during simulation. Specifically, AbsoluteTolerance is used to control the largest allowable absolute error at any step during simulation. It controls the error when a solution is small. Intuitively, when the solution approaches 0, AbsoluteTolerance is the threshold below which you do not worry about the accuracy of the solution since it is effectively 0. RelativeTolerance controls the relative error of a single step of the integrator. Intuitively, it controls the number of significant digits in a solution, except when it is smaller than the absolute tolerance, and −log10(RelativeTolerance) is the number of correct digits.AlgorithmAt each simulation step i, the solver estimates the local error e in the state j of the simulation. The solver reduces the size of time step i until the error of t
