error definition
 
Silly equation about the error definition (for 1-D):

L-1 error: \sum(abs(df))*dx;

L-2 error: \sqrt(\sum(abs(df)**2)*dx);

L-intfy error: \maxval(abs(df))

where df is the difference between the numerical result and the exact solution, dx is the mesh size.

Are these right?

Many thanks.
