比如要使UG中的一个实体进行旋转变换！
UG open API中说明使用：
uf5947_
Transform objects according to a previously defined matrix.
The upper limit on the number of objects to transform is 32767. The object types supported for non-uniform scaling are the same as those supported by non-uniform scaling in interactive Unigraphics.
函数原型如下：
extern void uf5947_ (
const double * rp1,
const tag_t * np2,
const int * ip3,
const int * ip4,
const int * ip5,
const int * ip6,
tag_t * nr7,
tag_t * nr8,
int * ir9 );
可是在使用此函数时返回值表明成功，但是实际没有完成；郁闷ing！！
程序代码如下：
/*****************************************************************************

** test_trans.c
