Improve generation of variables and assignemnts

2

We have the pattern: ``` double _t0; ... _t0=...; ``` Instead we should generate `double _t0 = ...;` This would significantly shorten the produced code snippets and make them more...

Compute the hessian matrix diagonal only

1

In many cases we need only the diagonal for the optimizer seeding. We can avoid computing the full matrix as in problems with many parameters will be costly. cc: @lmoneta.

Do not relocate the tape elements

1

In the current implementation of `clad::tape` we ensure the elements are contiguous. The `grow` operation relocates the elements when the size exceeds the tape capacity: https://github.com/vgvassilev/clad/blob/f242077c9b386a9711cdb257b1126a07b52c5006/include/clad/Differentiator/Tape.h#L119 Instead we should allocate...

Complain if signatures of the forward declaration and generated code mismatch

2

Clad builds a gradient with a specific signature. It also allows that gradient function signature to be forward-declared. However if both mismatch there are subtle crashes in CodeGen. We should...
