有没有具体的在fortran中编译matlab数学引擎的具体过程，我按刘志检的书做了，但是在dos环境下不能运行：libeng.def，libmex.def，libnix.def，libmat.def和Maflab.def这几个命令，生成连接库，所以想请教有没有具体的编译步骤，或是参考文献，非常希望大家帮助。

你的意思是不是fortran调用matlab程序？下面的文章应该对你有帮助 如何由Fortran中呼叫MATLAB的M檔案 基本的作法是先將M檔案轉換為.dll檔 再由Fortran去呼叫之 程式是使用 Matlab 6.5.1 Matlab compiler v3.0.1 Compaq Visual Fortran Pro v6.6.0 (CVF) (Compaq bought DEC and HP bought Compaq) 原始m檔案為 function b= matlabinc(a) % Increment given argument a and return result b to caller, displaying both on screen as well disp(a) explore(a) b = a + 1; disp(b) explore(b) 使用以下的方式compile 為DLL eval(['mcc -t -L C -W lib:QuGeneLib -T link:lib -h ' progName '.m libmmfile.mlib']) %如果m 檔案中有繪圖請使用以下方式 %eval(['mcc -B sgl -t -L C -W libhg:QuGeneLib -T link:lib -h ' progName '.m libmmfile.mlib']) 以下為原始檔與描述 This heavily commented Fortran program serves as a simple example on how a MATLAB .m file can be called from Fortran. Suitable if this is your first time trying this. The basic mechanism is to pack the C-compiled .m into a .dll and link to it from Fortran. Argument and result xfer mechanism is explained so that program can be easily expanded. 程式開始 以下藍色部分為MATLAB中使用方式 藍色以下部分為Fortran中使用方式 program test !=============================================================================================================== ! ! This program serves as a simple example on how to interface a Fortran program to Matlab, ! not the other way round which is well documented elsewhere. ! ! ! ENVIRONMENT ! This will work using the following environment on a Windows XPpro PC, other environments have not been tested ! but may work as well. ! ! * Matlab v6.5.1 R13 SP1 ! * Matlab compiler v3.0.1 ! * Compaq Visual Fortran Pro v6.6.0 (CVF) (Compaq bought DEC and HP bought Compaq) ! ! ! OVERVIEW ! We start with a simple .m script and create C-code from it, which is then compiled and placed into a .dll. ! This process is performed fairly automatic in the Matlab environment. ! ! Now we write a Fortran program that calls this Matlab routine. For this to work properly we have to setup ! Matlab structures containing the data values (the mx array and pointers to it), take care of the underscores ! added to routine names in dll's, the way the arguments are referenced because the routine was generated ! from C-code and the fact that the routine resides in a dll. All this need only be done for the Matlab script ! we create, we may call any mx* routines in a normal Fortran fashion. All this is described in detail now. ! ! ! DETAIL ! Our task is to call the following Matlab script from a Fortran program. ! ! function b = matlabinc(a) ! % Increment given argument a and return result b to caller, displaying both on screen as well ! disp(a) ! explore(a) ! b = a + 1; ! disp(b) ! explore(b) ! ! We compile our Matlab script using a function like this ! ! function compileDLL(progName) ! % Compile the .m file given and place result into a dll ! eval(['mcc -t -L C -W lib:QuGeneLib -T link:lib -h ' progName '.m libmmfile.mlib']) ! % Use this line instead if you call graphics routines in your .m file ! %eval(['mcc -B sgl -t -L C -W libhg:QuGeneLib -T link:lib -h ' progName '.m libmmfile.mlib']) ! ! This will create two files, QuGeneLib.lib and QuGeneLib.dll. The.lib file contains information for the Fortran ! compiler on what is in the .dll file. The .dll is the dynamic link library that contains our compiled Matlab ! routine. Copy both to the Fortran development directory were the .f90 files live. Also copy all Matlab .dll's ! you are using to the same location, libmx.dll is one you will definitely need. If you call graphics routines ! you will also need sgl.dll and you have to place FigureMenuBar.fig and FigureToolBar.fig into the path of ! the executing Fortran program as well. ! ! In CVF use "project->add to project->files" and pick the QuGeneLib.lib file. Read through the comments in this ! Fortran program to understand how everything works. You can use the DOS command ! ! dumpbin/exports libmx.lib ! ! or the Windows Dependency Walker !!http://www.dependencywalker.com/ ! ! to see the names of the routines included in the corresponding .dll, this is what has to go into the ! ALIAS directive when defining the interface for the C routine in the dll with the !DEC$ compiler statement. ! You will note an added underscore and sometimes also a @number after the name. The number indicates the number ! of bytes used for arguments. Also, C is case sensitive so cases in routine names must match. ! ! Note: You do not need to do this for any mx* routines, Matlab has defined an API for all of these. Although you will ! encounter a name such as MXCOPYPTRTOREAL8@12 in libmx.lib, you have to call mxCopyPtrToReal8 instead. ! ! The main way of achieving data transfer between Fortran and the Matlab C program created from our .m file script ! is via the mx routines supplied by Matlab in the libmx.dll. Read through Matlab HELP titled ! "External Interfaces/API Reference: Fortran MX-Functions" before expanding this example. ! ! Note: You do not need to define any interfaces, pointers etc for the mx* routines. You do also not need ! to call loadlibrary or getprocaddress for the mx* routines. It will not work if you do any of this. ! ! !
