jacobi scaling can mangle the jacbian matrix #68

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
In rare cases where the column norm of the jacobian matrix is tiny, the logic 
for estimating the scaling matrix used for jacobi scaling is broken and can 
corrupt the matrix so that the solver returns bad solutions.

https://ceres-solver-review.googlesource.com/#/c/1752/ hopefully fixes this.
