* <li> Computing errors:
- * The function @p integrate_difference performs the calculation of the error
- * between the finite element solution and a given (continuous) reference
- * function in different norms. The integration is performed using a given
- * quadrature formulae and assumes that the given finite element objects equals
- * that used for the computation of the solution.

*
* The result is stored in a vector (named @p difference), where each entry
* equals the given norm of the difference on a cell. The order of entries
* Compute the error of the
* finite element solution.
* Integrate the difference
- * between a finite element
- * function and a reference
- * function, which is given as a
- * continuous function object.
+ * between a reference function
+ * which is given as a continuous
+ * function object, and a finite
+ * element function.

* The value of @p exponent is
* used for computing $L^p$-norms
