MAGMA Forum

I found an SC15 poster that said all four dense symmetric tridiagonal eigensolvers (QR, divide and conquer, bisection and inverse iteration, and MRRR) were included in MAGMA. When I downloaded 2.0, however, I only saw the D&C driver. What is the actual status of the others?

For complex matrices:
magma_[cz]heevd* uses divide-and-conquer
magma_[cz]heevr* uses MRRR
magma_[cz]heevx* uses QR iteration if MagmaRangeAll, or bisection if MagmaRangeV or MagmaRangeI.

For real matrices, only divide-and-conquer is available:
magma_[sd]syevd*

BTW, MAGMA is at version 2.5, not 2.0.
