Matrix_<T> serialization and I/O
These methods are at namespace scope but are logically part of the Vector classes. These deal with reading and writing Vectors from and to streams, which places an additional requirement on the element type T: the element must support the same operation you are trying to do on the Vector as a whole.

Detailed Description

template<class ELT>
class SimTK::MatrixView_< ELT >

This class is identical to a Matrix_; it is used only to manage the C++ rules for when copy constructors are called by introducing a separate type to prevent certain allowed optimizations from occuring when we don't want them.

Despite the name, this may be an owner if a Matrix_ is recast to a MatrixView_. However, there are no owner constructors for MatrixView_.

Matrix assignment to an element sets only the *diagonal* elements to the indicated value; everything else is set to zero.

This is particularly useful for setting a Matrix to zero or to the identity; for other values it creates a Matrix which acts like the scalar. That is, if the scalar is s and we do M=s, then multiplying another Matrix B by the resulting diagonal matrix M gives the same result as multiplying B by s. That is (M=s)*B == s*B.

NOTE: this must be overridden for Vector and RowVector since then scalar assignment is defined to copy the scalar to every element.
