306ce33e1c BDCSVD: Streamline compute() and copyUV() 2013-08-07 16:34:34 +01:00
Hauke Heibel
8f4d93a4b7 Fix compilation. 
The Matrix is required to be mutable but it also needs to be a reference and
temporaries do not bind to non-const references - thus we need a hack and
cast away the constness.

68168e9eae MatrixFunctions: replace eval() by nested. 
This eliminates an unnecessary copy in some situations, e.g. Map.
