aaaade4b3d the Index types change. 
As discussed on the list (too long to explain here).

9962c59b56 * implement the corner() API change: new methods topLeftCorner() etc 
* get rid of BlockReturnType: it was not needed, and code was not always using it consistently anyway
* add topRows(), leftCols(), bottomRows(), rightCols()
* add corners unit-test covering all of that
* adapt docs, expand "porting from eigen 2 to 3"
* adapt Eigen2Support

9a4a08da46 Creation of the Polynomials module with the following features: 
* convenient functions:
  - Horner and stabilized Horner evaluation
  - polynomial coefficients from a set of given roots
  - Cauchy bounds
* a QR based polynomial solver

2d7bd1ec91 Make MatrixFunctions tests more robust. 
* Use absolute error instead of relative error.
* Test on well-conditioned matrices.
* Do not repeat the same test g_repeat times (bug fix).
* Correct diagnostic output in matrix_exponential.cpp .

a7d085eb4e NonLinearOptimization : clean 'mode' handling from the old minpack code : 
* this is actually a boolean, not an int
* use a better name
* can be set at initialization time instead of bloating all methods signatures

67ce07ea83 matrix_function test: replace expm(A).inverse() by expm(-A) 
The latter is more stable. This fixes one of the issues with the test.
Also, make typedef's in MatrixFunctionReturnValue public; this is
necessary to get the test to compile.

b18f737aa1 Test matrix functions with matrices with clustered imaginary eivals. 
The idea is that these test MatrixFunction::swapEntriesInSchur(),
which is not covered by existing tests. This did not work out as
expected, but nevertheless it is a good test so I left it in.

ee0e39284c Replace the qr factorization from (c)minpack (qrfac) by Eigen's own stuff. 
Results as checked by unit tests are very slightly worse, but not much.

858539a6af Use matrices with clustered eigenvalues in matrix function test. 
This is in order to get better code coverage.
Test matrix_function_3 now fails regularly because ComplexSchur
reaches the max number of iterations; further study needed.

adb2170eb8 removed Eigen::Complex class since it offered insufficient advantage over std::complex when sane real,imag structure packing is assumed.

f54a2a0484 Add support for general matrix functions. 
This does the job but it is only a first version. Further plans:
improved docs, more tests, improve code by refactoring, add convenience
functions for sine, cosine, sinh, cosh, and (eventually) add the matrix
logarithm.
