发帖数: 943 | 1 "学一门全新的语言，一两天就足够熟练了" Wow, I do not think so. The big
difference between Fortran and C++ is the fundamental idea behind the design
of the code. The design of the code will be significantly different. in a
Structure or OOP paradigm. Speedwise, Fortran always wins. Reusability of
the code is way much better under OOP. my another 2 cents. |

发帖数: 4162 | 11 常年只用fortran干事
最近要从网上实时拉东西下来算
到处看了看
似乎可以用fortran做计算内核，用python拉东西下来
现在的问题是f2py可以做这个事情
不过看了很多例子，都是很简单的一个subroutine文件啥的
我的情况是一个自己写library，几十个subroutine的文件
然后用一个module文件作为头
这样的情况f2py可以对付么？ |

发帖数: 261 | 13 因异地写论文期间,曾经在自己的电脑上安装了intel fortran,用的是实验室给我买的license. 这个license在实验室电脑上也安装过.
后来我把软件卸载了.但卸载的不完全,因为和MS Visual Studio整合在一起了,很难卸载干净.再加上有其他原因,我干脆把硬盘重装了.
过了2年,导师突然发信询问,我是不是没有卸载完全,说他装不上.
写信的语气有点质询的感觉,让人很不舒服.
我重新验证了一遍,可以用注册文件*.lic安装,无须网络验证.
另外,难道没有别的办法可以在实验室其他机器上重新安装么? 如果一个license被其他人安装过,(不完全)卸载, 或者硬盘被格式化过,
难道其他人就不能安装了?就没办法找客服解决么?
我现在在工业界,完全不求着他.不过我还是立马写信告诉他我已卸载,而且告诉他可以用
注册文件直接注册.
导师连个thank you都不回复一下.让人看着怪怪的.
我的问题:
如何确保我的机器完全删除? version: intel fortran composer XE 2013.
总不至于我要再安装一遍,然后再卸载?

发帖数: 104 | 14 For finance research, any language is ok.
The finance research mostly uses the mathmatic part
of the computer language, which is always some simple
math function or expression within the interger, real
or long real(double real) data type.
In most popular computer languages, such as MSVC, Borland
C++,
Fortran, Pascal. even Java, or VB, all of tham can handle
this easy mathmatic application without any problem.
To be in more detail.
Fortran is focusing on its efficiently solving advanced

发帖数: 97 | 17 Anyone knows any sample fortran routine for coordinate transformation?
I would like do such a calculation for stresses ans strains:
[C]=[A][B][A]^T
Any tips are thankful.
I already know the matrix calulation fortran flow for A= B*C like:
do i=1,3
do j=1,3
A(i,j)=0.0
do k=1,3
A(i,j)=B(i,k)*C(k,j)+A(i,j)
enddo

Someone told me to use lapack library, I think it may be a simpler
solution like above... |

发帖数: 339 | 25 Suggest have a poll on this:-)
I don't like Fortran, it is hard to read or understand, it
is case
insensitive, its variable/subroutine names must be less than
six
character (yeah, some compilers allow you to have more than
six chars,
but this is the FORTRAN 77 standard, if you dare to use more
than
six chars, you may have big trouble to port it to another
system).
, it's full of gotos, jumping up and down like a hopper.
It doesn't support structure or class,
it does not have dynamical memory all |

发帖数: 339 | 26 I use Fortran frequently, mostly because some old program was
written in that language, it cost too much time to write a new
one, patchy work.
As for your point of "simple", let me say this: it is no more
complicated to write the program in any other language. On the
other hand, for some more complicated works, it is very difficult
or ugly if you use FORTRAN.
As for "clean", I noted that you used lots of "end dos", strictly
speaking, that's not part of F77 standard. To ensure it runs
everywhere, |

FORTRAN是不是还那么费劲。 |

发帖数: 71 | 31 I think, a number generated during estimation is too close to zero that SAS
and R regarded it as zero or too large to be out of range allowed by SAS and
R because in Fortran results a parameter estimate is very large. I am not
sure if it is the reason. Since SAS and R show no solution, I wonder if I
can believe Fortran results. |

发帖数: 1522 | 48 How can I convert an integer to a character in fortran?
For example, IY=1984, 1985, ..., and IY is changable, and I wish the character
YEAR would be 1984, 1985, ..., too, and it could be changed following IY. I
try to use the function achar and char, and they don't work as my expectation.
Actually, my final purpose is to concatenate characters (strings) with integer
and create a new string. Please tell me how I can do. Thanks. |

问题如下：
函数是用MONT CARLO方法计算圆周率。单线程计算函数两次共耗费大约是97；而两个线

环境：
CPU: i7920 4核
操作系统：Windows Vista
编译器:Fortran 90
程序如下：
多线程主程序：

integer(INT_PTR_KIND())::Threads_Handle(n_thread),waitresult,cend,retlog,
