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.
