I have now migrated to Intel Visual Fortran and the problem in my initial post has vanished, as mentioned by David. This leads me to a question: Does the standard say anything about the indexing conventions? I.e. does Compaq Fortran comply with the Fortran 95 standard, even though the cod...
Rule of thumb: every scalar in an array-indexing expression reduces the rank of the resulting array for 1. For example, if A is an array, A(1) has rank 1-1=0=scalar, while A(1:2) or A([1,2]) is still a rank-1 array. Thank you very much! Translate 0 Kudos Copy link Repl...

C programming language has been designed this way, so indexing from 0 is inherent to the language. However, some languages give user a choice to start index from zero or any other positive integer. For an example, in Fortran, when an array is declared with integer a(10) (an array of ...
Therefore,reshape()converts the original array’s eight elements to the new array in the following order of indices when usingorder="F": This diagram shows the order of the indices when you use Fortran-like indexing. In this case, the first index is changing faster because it changes for ...
order :{'C', 'F'}, optional. Determines whether the indices should be viewed as indexing in row-major (C-style) or column-major (Fortran-style) order. 可选,一般默认就好。 具体过程解释:以下图情况下的 np.unravel_index(np.argmax(x), x.shape) 为例, 也就是np.unravel_index(8, (3,...
An associative array is defined as an array that uses strings as indexes for array elements, unlike traditional arrays in languages like C or FORTRAN which use numeric indexes. It allows variables to be accessed using string indices, enabling the implementation of composite data types similar to ...
多数情况下,它们直接映射到相应的机器表示,这使得“读写磁盘上的二进制数据流”以及“集成低级语言代码(如C、Fortran)”等工作变得更加简单。数值型dtype的命名方式相同:一个类型名(如float或int),后面跟一个用于表示各元素位长的数字。标准的双精度浮点值(即Python中的float对象)需要占用8字节(即64位)。因此,该...
I know it uses a Fortran way of accessing information, so, given an N-D array, the dimension order that will change faster during eg. a reshape will be 1,2,3 etc. (and not N,N-1,N-2 etc as in C-manner). One would expect that, when one tries to reduce the dimensions of an...
The fundamental object of NumPy is its ndarray (or numpy.array), an n-dimensional array that is also present in some form in array-oriented languages such as Fortran 90, R, and MATLAB, as well as predecessors APL and J.Let’s start things off by forming a 3-dimensional array with 36...
