As I understand it pass-by-reference is not supported from C++ to Fortran is not supported, or at least not part of the language. Nevertheless it seems to enable passing a value to a Fortran routine whose argument is not declared to have the 'value' attribute. The code below illustrates ...
Fortran程序和它的子例程之间用地址传递(pass-by-reference)方案来进行通信: 当调用子例程时,主程序传递一个指针来指向实参表中各个参数的存储位置。 子例程查找调用程序所指向的内存位置, 以获得它需要的形参值。 必须确保调用参数列表中的值与子例程的调用参数在个数、 类型、 次序方面都完全匹配。 6.1.4 传递...
传递的方式有两种: 传址(By reference):高效,可回传,节约内存 传值(By Value):不可回传,速度慢,浪费内存,安全 建议: 严格匹配实参和虚参,包括数据类型、Kind值、数组维度等; 未特别指定可选参数时,严格匹配参数个数; 大多数情况下,实参和虚参应该使用不同的名字。实参命名应考虑在调用者中的标识,虚参命名...

I have no trouble passing a simple integer or float by reference or by value to a Fortran subroutine but Ican not do the same with an Array. I get an error that indicates that the subroutine cant be found but itcan be found if i change the arguement to not be an array. Any ...
