Create a Fortran compiling environment in Linux-general Linux technology-Linux programming and kernel information. For more information, see the following. In the past few days, it's okay to get the Fortran in Linux. According to Internet searches, Intel compiler is the most famous and best-to-use. So I searched and downloaded the file online. However, because it was on CERNET, it could not go to Intel's of

written header files or explicitly User-Defined generation rules. for Fortran 90 programming, the concomitant *. MOD files play the role of header files in C/C ++. because they are automatically generated concomitantly with corresponding object files containing implementation of modules, there are no explicit User-Defined generation rules for these *. MOD files. hence, it is useless to put these *. MOD files into the variable built_sources. if no oth

Rewind and BACKSPACE of Fortran languageIn the early Fortran specification and compilers, backspace and rewind were indeed related to sequential storage devices such as tape drives. Later, it becomes a device-independent statement. However, it may be related to file mode.Rewind is still very common now. If your program needs to read the same text format data file two times, when you have finished reading th

Matrix multiplication (2015.09.28)Answer: Vector point multiplication function dot_product (A, b), matrix multiplication function Matmul (A, b), matrix multiplication includes vector point multiplication. For example Program Matpro Implicit noneReal:: A (3), B (3), C (3,1) A (1) =1.0A (2) =2.0A (3) =3.0B (1) =4.0B (2) =3.4B (3) =2.1C (:, 1) =b (:)Write (*,*) dot_product (A, B), Matmul (A,C) End Program Matpro The result is the same.Use of the process of

This document details how to install the Fortran compiler in Linux. 1. Open http://gcc.gnu.org/wiki/GFortranBinaries in a browser 2. Download the 2-in Linux version, my Linux is fedora16, x86-64, so I chose http://gcc.gnu.org/wiki/gfortranbinariesunder64-bit amd-compatible processors (x86_64, amd64, intel64, em64t)2.1 find a file and download it to the local machine, I chose http://gfortran.com/download/x86_64/nightlies/gcc-trunk-20120601-r1

I told you how the subroutine can't pass a mutable array.When writing a Fortran program, to achieve a specific function of the matrix, such as the Gauss method to solve the linear equations, many times the subroutine does not know the size of the matrix, such as the finite element program first to use the program to obtain the total stiffness matrix and then gross position just passed in the sub-program to solve the matrix equation. So implementing su

Software developers are often faced with a difficult choice when developing product-level code, you always want your code to be superior, which means you need to compile it at a high level of optimization, and you may want to debug the binary in your product, rather than the source files that are not optimized at compile time. If you've tried debugging optimized code, you probably already know the difficulty: Source code statements do not execute sequentially, or they do not when you want them

Help the cluster to install fortran and mathematica-general Linux technology-Linux technology and application information. The following is a detailed description. Hero I now have 8 nodes in the sugon t4000 series, with 2 CPUs per node, 4 cores per CPU, and linux update 5 operating system. I want to install the parallel fortran editor to use all nodes, but I am a newbie to the cluster. Which editor do you

Please refer to the following link for more information: Can programs written in the windows fortran environment run in linux-Linux Enterprise Application-Linux server application. I have never considered this issue during programming. I usually write it on my own machine, but now I want to run it on the server. I would like to ask if you can run it directly in the linux fortran compiler, because the progra

records to describe the unit, and each read-in or write is a record. The length of the record is determined at Open and cannot be changed in the future. 　　If you need to change, you can only Close the Open later. The record length represents a multiple of the read 4-byte length under some compilers, and a specified 4 indicates a record length of 16 bytes. Some compilers directly represent the number of bytes logged, and a 4 indicates a record length of 4 bytes. This issue requires reference to

By default, it is not possible to debug the Fortran Program in GDB. There are some tips. For FORTRAN77 programs, use G77 to compile and G77-g-o hello. f, and then use GDB hello to enable the gdb debugging interface. At this time, inputting l cannot list the code, because when debugging Fortran, you must manually specify the name of the function, subroutine, or program, so here we need to enter l main _ (

FORTRAN has two kinds of subprograms: subroutine and function. usually, subroutine is a combination of several procedures generating side effects without returning values, while the purpose of function is to return values after some operations. in fact, returning values can be implemented in a subroutine by setting some of the formal parameter propertiesIntent (out)OrIntent (inout). Compared to function calling, an inconvenience for returning values f

The first high-level language was born in 1945, the German Chu translated his Z-4 computer design plan Calcul, a few months earlier than the first computer;! The first high-level language to be achieved in the computer is the Shortcode, which was successfully developed by American Uyuni in 1952;The first high-level language that is still popular today is the American computer scientist Backus Design, while really getting promoted to use,And in 1956 the Fortr
