Function | Consistency check: test if all elements of a vector are identical |

| Description | The vector X is analyzed. If all elements are identical, TRUE (1) is returned, otherwise FALSE (0). In order to be identical, the bit representation of all elements must be the same. Thus, +0 and −0 are treated as being different from each other. The same holds for the various types of NAN. |

| Return value | TRUE (1) or FALSE (0) |
