Listed on this page are additional functions used frequently in dynamic simulation models that are not defined as part of MathML 2.
This capability is provided in DAVEML through use of the breakpointDef, griddedTableDef, ungriddedTableDef, and function elements of DAVEML.
See the DAVEML reference manual for more information about function representations.
This function provides a twoargument arc tangent function, similar to those available in ANSI C and FORTRAN math libraries as well as Microsoft Excel and Mathworks Matlab and Simulink products.
The following definition from the GNU 4.0.1 gcc man
page is reproduced for reference:
The atan2 function computes the principal value of the arc tangent of y/x, using the signs of both arguments to determine the quadrant of the return value.
The first argument (y) represents the opposite side of the angle and the second (x) the adjacent, nonhypotenuse side. The resultant represents the angle, in radians, in the range of –π to +π.
Implementation of this function is up to the processing application.
