e97529c2e3 doc : update code, mention examples 2010-01-27 08:14:50 +01:00

afb9bf6281 use PlanarRotation<> instead of handmade givens rotation in cminpack code 
+ cleaning.
This results in some more memory being used, but not much.

113995355b get rid of ei_qform + lot of other cleaning, now that we do not depend on 
minpack qr factorization.

91561cded4 use a plain matrix to store the upper triangular matrix 'R', instead 
of the "compact inside a vector" scheme used by fortran/minpack.
The most difficult part is to fix all related code. Tests pass.

1403cea087 fix a bug introduced between the cminpack version of Manolis Lourakis and 
the one from Frédéric Devernay.
Here, we want to compute the max over the column, the -1 is not needed in
fortran because indices start at 1, contrary to c/c++.

9651e0c503 Use eigen methods for solving triangular systems. We loose again very 
slightly on both speed and precision on some tests.

92be7f461b define ei_lmpar2() that takes a ColPivHouseholderQR as argument. We still 
need to keep the old one around, though.

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.

2026ea7ff2 Coax doxygen in producing better docs for MatrixFunctions. 
The //@{ ... //@} in unsupported/Eigen/MatrixFunctions for some reason
caused doxygen to list the constructor of the MatrixExponential class
as a separate function in the MatrixFunctions module without any reference
to the class; very confusing.
