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：

Error using mex

这些错误发生的我的功能之一是：

    complex<double> MIEsolution::Spherical_Bessel_function_2k(unsigned n,complex<double> z){

    complex<double> Sb2k;

        Sb2k = sph_besselY(n, z);

    return Sb2k;

}

关键是这个库将一些 Fortran 代码与 C++ 连接起来。例如，该sph_besselY函数将调用适当的 Fortran 代码zbesy_wrap。

我想以某种方式编译 Fortran 函数吗？我以与网页相同的方式安装库。另外，我正在将库导入到我的代码中，如下所示：

#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：

编译 simpleTest.cpp 错误

在 Code::Blocks IDE 中，我在Project->Build Options...->Linker Settings->Other linker options:文本框中设置了这个标志。
至于mex，我不知道这个mex GUSTAVsolution.cpp -lcomplex_bessel是否可以工作，但是您肯定应该以某种方式添加此链接器标志！
