Fortran 中,调用函数或子程序时,默认将实参的地址传递给形参,称为地址传递或引用传递。究其原因,是因为Fortran主要针对数值计算,参数多为大型数组(二维数组称矩阵),如果采用值传递,会复制实参的一个拷贝给形参,占用时间和内存,而地址传递则仅仅将实参数组的首地址传递给形参,没有时间和内存冗余。
So that one could define a generic function first_or_second below: interface first_or_second module procedure first, second end interface This is NOT so. Explanation The reason is that Fortran 90 allows procedures to be called by name (keyword) arguments. The following real :: b integer ::...
