7ee084f82f Leverage triangular square root in matrix log. 2011-08-25 07:42:32 +01:00

c01ed935dd Split code for (quasi)triangular matrices from MatrixSquareRoot. 
This way, (quasi)triangular matrices can avoid the costly Schur decomposition.

42e2578ef9 the min/max macros to detect unprotected min/max were undefined by some std header, 
so let's declare them after and do the respective fixes ;)

a660e6425c fix a bug where some rotations were not initialized 
They actually were in the original minpack code, this is a bug introduced
by our migration.

87ac09daa8 Simplify the use of custom scalar types, the rule is to never directly call a standard math function using std:: but rather put a using std::foo before and simply call foo: 
using std::max;
max(a,b);

dac4bb640a Fix compilation error under GCC 4.5. 
That version is stricter in forcing function prototype and definition
to match.

6b4e215710 Implement matrix square root for complex matrices. 
I hope to implement the real case soon, but it's a bit more
complicated due to the 2-by-2 blocks in the real Schur decomposition.
