Mass metric matrix
Web21 de may. de 2015 · M ( u n + 1 − u n d t) = − c K u n and thus even though we are using an explicit time stepping scheme we still have to solve a linear system. This is obviously a major problem since the primary advantage of using explicit schemes is to NOT have to solve a linear system. Web26 de ene. de 2015 · So: Yes, your matrix is an appropriate way of writing a metric tensor. Yes, every matrix IS a 2-tensor (always "in" a coordinate sytem) BUT. this matrix depends on the choosen basis. And the other types of 2-tensors are bilinear maps $$ V \times V^* \rightarrow \mathbb {R} \quad \text {and} \quad V^* \times V^* \rightarrow \mathbb {R} $$ …
