• createmats - a function with the same signature as TaoTermCreateHessianMatrices()

Calling sequence of createmats

• f - the TaoTerm

• H - (optional) a matrix of the appropriate type and size for the Hessian of term

• Hpre - (optional) a matrix of the appropriate type and size for constructing a preconditioner for the Hessian of term
