- Remove the GeneralMatrix(const ConstVector &) constructor, since it is hides
a memory allocation (copying the ConstVector into a fresh Vector). This
helped detecting and fixing several unneeded memory allocations. Some other
memory allocations are now more visible (with an explicit Vector{}
constructor).
- Add checks in GeneralMatrix(Vector, …) and ConstGeneralMatrix(ConstVector, …)
constructors for verifying that the {Const,}Vector has unit-stride (this was
an implicit assumption so far) and is large enough for storing rows*cols
elements.
- Add GeneralMatrix::operator=(const ConstGeneralMatrix &).
- Delete ConstGeneralMatrix::operator=().
- these classes now encapsulate a std::shared_ptr<{const, }double>, so that
they do not perform memory management, and several {Const,}Vector instances
can transparently share the same underlying data
- make converting constructor from ConstVector to Vector explicit, since that
entails memory allocation (but the reverse conversion is almost costless, so
keep it implicit); do the same for GeneralMatrix/ConstGeneralMatrix,
TwoDMatrix/ConstTwoDMatrix
- remove the constructors that were extracting a row/column from a matrix, and
replace them by getRow() and getCol() methods on {Const,}GeneralMatrix
- rename and change the API of the complex version Vector::add(), so that it is
explicit that it deals with complex numbers
- add constructors that take a MATLAB mxArray
