Thank you.<br>
TFQMR works well now, however TCQMR doesn't. Although latter was

issue earlier. When VecDot changed from using custom code to BLAS
xDOT, the conjugation definition was accidentally changed. If you
pull after this patch, TFQMR will work for your problem again.

This is not possible:<br>
<br>

>> find(diag(A)==0)<br>
ans =<br>
Empty matrix: 0-by-1<br>
<br>

ans = (1,1) 7.999999999999997e+002
+6.316546778308559e-009i<br>
<br>
Sorry, I forgot to mention that this is double complex
matrix and vector. Have you read it as real double?

Is this possible to look up changes in one file

<div>$ hg log src/ksp/ksp/impls/tfqmr/</div>
