rister_c[2] = atof(rister_z);
UF_CSYS_map_point (UF_CSYS_ROOT_WCS_COORDS, rister_c,
UF_CSYS_ROOT_COORDS, output_point);
UF_MTX3_z_vec (matrix_values, rotation_axis);
rotation_axis[2] = 0.0-rotation_axis[2];
UF_MTX3_rotate_about_axis (rotation_axis, rotation_angle, new_matrix_values);
UF_MTX3_y_vec (matrix_values, rotation_axis);
UF_CSYS_set_wcs(wcs_id);
UF_CSYS_set_wcs_display (1);
UF_OBJ_delete_object(csys_id);
}

UF_MTX3_rotate_about_axis:结果是绝对坐标下的matrix,该怎么得到在新建的

坐标下旋转后的matrix 啊???
