complex_Bessel_function库的编译——与Fortran代码的链接——mex文件

Compiling of complex_Bessel_function library - linking with Fortran code - mex file

我制作了一个.cpp代码,它使用以下在线库:

复杂的贝塞尔函数。

我想用我的代码制作一个.mex文件。当我打字时:

mex GUSTAVsolution.cpp

Matlab给出以下错误:

发生这些错误的功能之一是:

complex<double> MIEsolution::Spherical_Bessel_function_2k(unsigned n,complex<double> z){
complex<double> Sb2k;
Sb2k = sph_besselY(n, z);
return Sb2k;
}

重点是这个库将一些Fortran代码与C++连接起来。例如,sph_besselY函数将调用相应的Fortran代码zbesy_wrap

我是否应该以某种方式编译Fortran函数?我以与网页相同的方式安装了图书馆。此外,我正在将库导入到我的代码中,如下所示:

#include <complex_bessel.h>
要修复此问题,请添加链接器标志-lcomplex_bessel,如下所示:

编译simpleTest.cpp错误

在Code::Blocks IDE中,我在Project->Build Options...->Linker Settings->Other linker options:文本框中设置了此标志
至于mex,我不知道这个mex GUSTAVsolution.cpp -lcomplex_bessel是否能工作,但可以肯定的是,你应该以某种方式添加这个链接器标志!
