14 /* Some notes on Eigen's static assertion mechanism:
15  *
16  * - in EIGEN_STATIC_ASSERT(CONDITION,MSG) the parameter CONDITION must be a compile time boolean
17  * expression, and MSG an enum listed in struct internal::static_assertion<true>
18  *
19  * - define EIGEN_NO_STATIC_ASSERT to disable them (and save compilation time)
20  * in that case, the static assertion is converted to the following runtime assert:
21  * eigen_assert(CONDITION && "MSG")
22  *
23  * - currently EIGEN_STATIC_ASSERT can only be used in function scope
24  *
