会VC的富翁看一下，这个头文件如何定义成DELPHI？(300分)

找到一个射影变换的头文件，本人VC的只能看懂一点点，最后的matrixT的意思如何理解？

// _NO_NAMESPACE: Define this macro to remove namespace support.
//
// _NO_EXCEPTION: Define this macro to remove exception handling
// and use old style of error handling using function.
//
// _NO_TEMPLATE: If this macro is defined matrix class ofdo
uble
// type will be generated by default. You can also
// generate a different type of matrix like float.

这里不是说了吗?晕.....

// 估计你的困惑在C++的模板上，找本书翻一下

# define MAT_TEMPLATE
# define matrixT matrix // matrixT 代表 matrix
# ifdef MATRIX_TYPE

# else

# endif
#endif

Ｃ＋＋中的模板是否和ＶＣＬ中的ＴＣＬＡＳＳ有相同点
如：matrixT=class of matrix
或者是为了定义类的数组做准备，如
matrixT=array of matrix
或者是其他概念，定义摸板是为了什么样的应用需要呢？

刚才看了点文章，摸板简单说就是容器＋算法，对吧？
matrix是一个自己定义的摸板类,它要么只是个简单的容器,要么还要实现一定的算法.
这样理解是否恰当?

delphi有条件编译的吗？

delphi有条件编译!

多人接受答案了。
