- * @brief Reference to selected subset of an array.
- *
- * A mask_array is a reference to the actual elements of an array specified
- * by a bitmask in the form of an array of bool. The way to get a
- * mask_array is to call operator[](valarray<bool>) on a valarray. The
- * returned mask_array then permits carrying operations out on the
- * referenced subset of elements in the original valarray.
- *
- * For example, if a mask_array is obtained using the array (false, true,
- * false, true) as an argument, the mask array has two elements referring
- * to array[1] and array[3] in the underlying array.
- *
- * @param Tp Element type.
