Speed Test of Functions in Double

Purpose

CppAD has a set of speed tests for just calculating functions (in double precision instead of an AD type). This section links to the source code the function value speed tests.

Running Tests

To build these speed tests, and run their correctness tests, execute the following commands starting in the Build Directory :

      cd speed/double

      make check_speed_double VERBOSE =1

You can then run the corresponding speed tests with the following command

./ speed_double speed seed

where seed is a positive integer. See speed_main for more options.
