IOW this is not an array of pointers to rows of data. In C/C++ it is more efficient to allocate a 2D array as a 1D array, possibly sticking the pointer into the C/C++ pointer[0] of the row table, then populate the row table for each stride into the blob that constitutes the 2D...
The libgomp runtime was modified to handle GOMP_MAP_STRUCTs initerators, which can result from the use of derived types (which I usedin test cases to implement arrays of pointers). libgomp expects aGOMP_MAP_STRUCT map to be followed immediately by a number of mapscorresponding to the fields...
This subroutine is essential for copying the output ofmatGetDirinto an array of pointers. After calling this function, each element ofycontains a pointer to a string. You can convert these strings to Fortran character arrays by passing each element ofyas the first argument tomxCopyPtrToCharacter...

指针( Pointers) 在大多数编程语言中,指针变量存储对象的内存地址。 但是,在Fortran中,指针是一种数据对象,它具有比仅存储内存地址更多的功能。 它包含有关特定对象的更多信息,如类型,等级,范围和内存地址。 指针通过分配或指针分配与目标相关联。 声明指针变量...
An entity with the POINTER attribute must not have the ALLOCATABLE, INTRINSIC, or TARGET attribute, and it must not be a coarray. Fortran pointers arenotthe same as integer pointers. For more information, see thePOINTER - Integerstatement. ...

最基本的内容:变量,输入输出,流程控制和程序结构。接下来是Fortran的数组,我认为这是Fortran语言最有价值的精华部分,因此特意放在了学习笔记靠后的部分,在学习了基本的语法和子程序等之后。注意,Fortran的字符集不包括中括号[],因此与c语言的风格不同,Fortran对数组分量的操作全都是使用小括号()的。
Be wary of array pointers and possible aliasing (accessing the same array element via different pointers). The compiler is conservative and won’t take any risk on overlapping memory locations. The compiler will recognize reduction idioms like summation and parallelize...
