Model.getGenConstrLogA()


Model.getGenConstrLogA()

getGenConstrLogA ( genconstr )

Retrieve the data associated with a general constraint of type LOGA. Calling this method for a general constraint of a different type leads to an exception. You can query the GenConstrType attribute to determine the type of the general constraint.

See also addGenConstrLogA for a description of the semantics of this general constraint type.

Arguments:

genc: The general constraint object.

Return value:

A tuple (xvar, yvar, a) that contains the data associated with the general constraint:

xvar (Var): The <span>$</span>x<span>$</span> variable.

yvar (Var): The <span>$</span>y<span>$</span> variable.

a (float): The base of the function.

Example usage:

  # y = log10(x)
  log10constr = model.addGenConstrLogA(x, y, 10.0, "log10")
  model.update()
  (xvar, yvar, a) = model.getGenConstrLogA(log10constr)
