Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This example solves the following nonlinear equations with function solveOneNonlinearEquation. The user can set the parameters, like "w" or "m", and can experiment with different start intervals. The following nonlinear equations are solved:
- 0 = u^2 - 1
- 0 = 3*u - sin(w*u) - 1
- 0 = p[1] + log(p[2]*u) - m*u
