Re: [ojAlgo-user] Complex SVD

[Anders P. <an...@op...>]

I don't get any compilation errors. Suppose it's a matter of compiler settings. Try changing those, or change the code so that your compiler with its current settings accepts it. /Anders

When you're done you may consider creating a patch file to update that branch. In that case please make sure all CVS modules (even the ones you don't use) compile.

We are working on upgrading to Java 7, but not fully there yet, especially on Mac due to some incompatibilities.  We would very much like to go with ojalgo, since it has continuing development and support.

Not shown are SingularValueDecomposition methods computeBidiagonal() and getBidiagonalQ1(), which also take time due to ComplexNumber.multiply().
