c++ - 编译 complex_Bessel_function 库 - 与 Fortran 代码链接 - mex 文件

Question

我制作了一个使用以下在线库的 .cpp 代码:

Complex_Bessel_functions .

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 函数将调用适当的 Fortran 代码 zbesy_wrap。

我应该以某种方式编译 Fortran 函数吗？我安装库的方式与网页相同。另外，我正在将库导入到我的代码中，就像这样:

#include <complex_bessel.h>

要解决此问题，请按照此处的建议添加链接器标志 -lcomplex_bessel:

Compile simpleTest.cpp errors

在 Code::Blocks IDE 中，我在 Project->Build Options...->Linker Settings->Other linker options: 文本框中设置了这个标志。
至于 mex，我不知道这个 mex GUSTAVsolution.cpp -lcomplex_bessel 是否能正常工作，但你肯定应该以某种方式添加这个链接器标志!
