6 January 2008
- LevinIntegrate:
- Added AmplitudeEvaluationMonitor, OscillatorsEvaluationMonitor, and OscillatorDerivativesEvaluationMonitor options.
- In warnings, improved information about location of problem areas of integrand.
18 December 2007
- LevinIntegrate:
- Added warning when global error suddenly increases.
- Changed usage of LinearSolve[m, b] to LinearSolve[m][b], allowing the solution of some integrals that previously failed to converge.
12 December 2007
- LevinIntegrate:
- Improved automatic singularity handling: the coordinate transformation is now applied once recursion reaches the depth specified in the new SingularityRecursion option.
- Performance improvements near endpoint singularities.
7 December 2007
- LevinIntegrate:
- Switched to using extended Chebyshev points as collocation nodes.
- New SingularityHandlingCollocationOrder option to avoid precision loss near endpoints due to unnecessarily high collocation order.
- Improved messages and warnings.
15 November 2007
- NAntiDerivative: First available for download.
16 October 2007
- Included CustomDefault.nb stylesheet to increase readability of included .nb files.
15 October 2007
- NDerivative: Updated with faster replacement for ND.
- SubscriptSymbols: Allowed enabling / disabling by setting SubscriptSymbols = True / False.
9 October 2007
- LevinIntegrate: First available for download.
23 August 2007
- ApproximatelyEqual: First available for download.
20 June 2007
