**Absolute tolerance** - Absolute error tolerances that apply to the individual components of the solution vector. Absolute tolerance is a threshold value below which the value of the solution component is unimportant. The absolute error tolerances determine the accuracy when the solution approaches zero. | **Absolute tolerance** - Absolute error tolerances that apply to the individual components of the solution vector.

**Relative tolerance** - Relative error tolerance that applies to all components of the solution vector y. This tolerance 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 defined in Absolute tolerance. The default, 1e-3, corresponds to 0.1% accuracy. | **Relative tolerance** - Relative error tolerance that applies to all components of the solution vector y.
