[jira] [Created] (MATH-827) Replace class "LegendreGaussIntegrator"
with "IterativeLegendreGaussIntegrator" class
Gilles created MATH-827:
---------------------------
Summary: Replace class "LegendreGaussIntegrator" with "IterativeLegendreGaussIntegrator" class
Key: MATH-827
URL: https://issues.apache.org/jira/browse/MATH-827
Project: Commons Math
Issue Type: Task
Reporter: Gilles
Assignee: Gilles
Priority: Minor
Fix For: 3.1, 4.0
The "LegendreGaussIntegrator" class (in package "o.a.c.m.analysis.integration") has a misleading name. Internally, it uses the Legendre-Gauss quadrature rule on sub-intervals of the integration range but, additionally, it performs an iterative procedure to automatically determine the number of sub-intervals over which the rule will be successively applied.
The strict Gauss-Legendre quadrature scheme has now been implemented (cf. MATH-797) in package "o.a.c.m.analysis.integration.gauss".
I thus propose to:
# Deprecate "LegendreGaussIntegrator" in 3.1.
# Create a new "IterativeLegendreGaussIntegrator" class that will perform the same procedure as "LegendreGaussIntegrator" but will internally use the classes in package "o.a.c.m.analysis.integration.gauss" to perform the Gauss-Legendre quadrature part.
# Remove "LegendreGaussIntegrator" in 4.0.
