      com.numericalmethod.suanshu.analysis.integration.univariate.riemann.substitution.NoChangeOfVariable

public class NoChangeOfVariable
extends Substitution

This is a dummy substitution rule that does not change any variable. This is mainly for testing purpose.

We have,

 /b          /b
 | f(x) dx = | f(t) dt
 /a          /a
 

Field Summary

double	a the lower limit
double	b the upper limit
