overridevirtual

The only method any matrix class needs to implement.

Parameters

x	Is x on the above operation. It must be a vector!
y	Is y on the above operation
z	Is z on the above operation
alpha	Is alpha on the above operation
beta	Is beta on the above operation
opt	Indicates if is Transpose or not In this case the variable x represents the rhs and z the result of the preconditioning When used as a preconditioner y will be zero In fact, it will compute It computes but z and x can not overlap in memory.

Reimplemented from TPZMatrix< TVar >.
