Question

我制作了一个使用以下在线库的.cpp代码：

我想从我的代码中创建一个.mex文件。当我打字时：

mex GUSTAVsolution.cpp

Matlab给出了以下错误：

我发现这些错误的一个功能是：

    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，sph_besselY函数将调用相应的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了库。此外，我正在将库导入我的代码，如：

#include <complex_bessel.h>

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

Compile simpleTest.cpp errors

Code :: Blocks IDE中的

我在Project->Build Options...->Linker Settings->Other linker options:文本框中设置了这个标志对于mex，我不知道这个mex GUSTAVsolution.cpp -lcomplex_bessel是否会起作用，但是你肯定应该以某种方式添加这个链接器标志！

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