Numerical Quadrature

ISC 5226 - Spring 2016

**http://people.sc.fsu.edu/~jburkardt/classes/quad_2016/quad_2016.html**

**QUAD_2016** contains some information used when I taught the
numerical quadrature section of Professor Ming Ye's class ISC 5226,
"Numerical Methods for Earth and Environmental Sciences",
Friday, 25 March 2016 and Wednesday, 30 March 2016.

Functions f(x) to integrate:

- derf.m, integral from -3 to +3 is erf(3.0)-erf(-3.0);
- disc.m, integral from 0 to 1 is 10.
- expo.m, integral from 2 to 4 is exp(4.0)-exp(2.0).
- humps.m, integral from 0 to 2 is 34.9262...
- linear.m, integral from 0 to 1 is 4.
- ramp.m, integral from -1 to +1 is 3.0.
- roller.m, integral from 0 to 4 is - 2.9878...
- sine.m integral from 0 to pi is 2.
- velocity.m, integral from 0 to 24 is 345.22.

Quadrature methods:

- clenshaw_curtis.m, (specify N as number of points).
- gauss1.m
