simpson

integral= simpson(function, a, b) or integral= simpson(function, a, b, epsilon) returns the integral of FUNCTION(x) from A to B. If EPSILON is given, Simpson's rule is refined until that fractional accuracy is obtained. EPSILON defaults to 1.e-6. If the notvector= keyword is supplied and non-zero, then FUNCTION may not be called with a list of x values to return a list of results. By default, FUNCTION is assumed to be a vector function. If the function is very smooth, romberg may work better. Interpreted function, defined at i/romberg.i line 58SEE ALSO: romberg, max_doublings
