如图所示,提示为: Subscript #1 of the array INDEX has value 61 which is greater than the upper bound of 60 比如定义一个数组 real A(3,4),实际赋值时成了A(3,5)或A(4,4),这就造成了数组越界。 数组越界不属于语法错误,只能通过Debug来发现问题所在。
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，...
3.4.164 –xprefetch_auto_type=indirect_array_access 为间接访问的数组生成间接预取。 以生成直接内存访问预取的相同方式来生成由选项 -xprefetch_level={1|2|3} 指定的循环的间接预取。可添加前缀 no% 否定声明。 缺省值为 -xprefetch_auto_type=no%indirect_array_access。 要求-xprefetch=auto 以及优化级...

After this 4-dimensional array has been allocated, I need to access it from C (actually, C++). What is the best way to do this, preferably without parsing the array descriptors? I'd like to be able to access either individual elements (e g, scans(1,2,3,4)), and vectors...

or corner. The Jacobi method consists of approximating the square plate with a two-dimensional grid of points where a two-dimensional array is used to store the temperature at each of these points. Each iteration updates the elements of the array from the values computed at the previous step....
