Information

This example checks whether the function derivative is implemented correctly. If the derivative implementation is not correct, the model will stop with an assert statement.

Revisions

• April 22, 2016, by Michael Wetter:
  Changed accuarcy test in assertion to use the relative error because the magnitude of y is 1E5 and hence testing an absolute error is too stringent. This is for Buildings, issue 510.
• August 17, 2015 by Michael Wetter:
  Updated regression test to have slope that is different from one. This is for issue 303.
• October 4, 2014, by Michael Wetter:
  Added a high tolerance which is needed for OpenModelica to pass the assert statement.
• October 29, 2008, by Michael Wetter:
  First implementation.
