To use DiagonallyImplicit, you first need to load the Numerical Differential Equation Analysis Package using Needs["NumericalDifferentialEquationAnalysis`"].
The setting DiagonallyImplicit is similar to the setting Implicit, except that the matrix has no nonzero upper-triangular entries. See the tutorial "Numerical Differential Equation Analysis Package" for more information.
