midpt {cmna} | R Documentation |
rectangle method
Description
Use the rectangle method to integrate a function
Usage
midpt(f, a, b, m = 100)
Arguments
f |
function to integrate |
a |
the a-bound of integration |
b |
the b-bound of integration |
m |
the number of subintervals to calculate |
Details
The midpt
function uses the rectangle method to calculate
the integral of the function f
over the interval from
a
to b
. The parameter m
sets the number
of intervals to use when evaluating the rectangles. Additional
options are passed to the function f
when evaluating.
Value
the value of the integral
