... Model error: an economic model is only an approximation of a “real” phenomenon Data error: parameters of the model have to be estimated, forecasted, simulated or approximated; data may be missing; available data may not well reflect the true but unknown process Numerical errors: solving a model on a ...

Row Space, Column Space, and Null Space
... rank(M N ) ≤ rank N. Proof. The preceding discussion shows that the rows of M N are linear combinations of the rows of N . Therefore, the rows of M N are all contained in the row space of N . The row space of N is a subspace, so it’s closed under taking linear combinations of vectors. Hence, any lin ...

... 5. The temperatures (K) at the nodal points of a two dimensional system are shown. The left-side surface is held at a uniform temperature of 500oK, while the surface A is subjected to a convection boundary condition with a fluid temperature of 500oK and a heat transfer coefficient of 10 W/m2oK. Ca ...
