283c51cd5e Widen short-circuiting ReciprocalConditionNumberEstimate so we don't call InverseMatrixL1NormEstimate for dec.rows() <= 1. 2016-04-07 16:45:40 -07:00

74f64838c5 Updated the unary functors to use the numext implementation of typicall functions instead of the one provided in the standard library. The standard library functions aren't supported officially by cuda, so we're better off using the numext implementations. 2016-04-07 11:42:14 -07:00
