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 *
