Declaration

 D = FiniteDifferenceMatrix(numDerivs,x,leftBCDerivs,rightBCDerivs,orderOfAccuracy)

Parameters

• numDerivs derivative order to approximate
• x grid on which to build the stencil matrix
• leftBCDerivs derivative order enforced at the left boundary
• rightBCDerivs derivative order enforced at the right boundary
• orderOfAccuracy formal order of accuracy

Returns

• D differentiation matrix
