【中文标题】在 Ubuntu 14.04 和 matlab 2014Ra 上使用犰狳在 mex 中出现分段错误【英文标题】：Segmentation fault in mex with armadillo on Ubuntu 14.04 and matlab 2014Ra 【发布时间】：2015-07-30 08:41:24 【问题描述】：

我尝试将 mex 文件与犰狳线性代数库一起使用。一开始，我尝试了一个非常简单的程序，如下：

谁能帮帮我？

%%%% matlab脚本%%%%%%%

mex -larmadillo -lgfortran armaMex_demo.cpp
X = randn(5,5);
Y = randn(5,5);
% Run the demo using X and Y
Z = armaMex_demo(X,Y,3)

%%%%%%%%%%%%% mex 文件 %%%%%%

#include "armaMex.hpp"
#include <armadillo>
using namespace arma;
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
  
  // Check the number of input arguments.
  if (nrhs != 3)
    mexErrMsgTxt("Incorrect number of input arguments.");

  // Check type of input.
  if ( (mxGetClassID(prhs[0]) != mxDOUBLE_CLASS) || (mxGetClassID(prhs[1]) != mxDOUBLE_CLASS) )
    mexErrMsgTxt("Input must me of type double.");

  // Check if input is real.
  if ( (mxIsComplex(prhs[0])) || (mxIsComplex(prhs[1])) )
    mexErrMsgTxt("Input must be real.");

  // Create matrices X and Y from the first and second argument.
  mat X = armaGetPr(prhs[0]);
  mat Y = armaGetPr(prhs[1]);
  int c= armaGetScalar<int>(prhs[2]);  
  // Our calculations require that matrices must be of the same size 
  if ( size(X) != size(Y) )
    mexErrMsgTxt("Matrices should be of same size.");

  // Perform calculations
  mat A = X + Y;
  mat B = X % Y;  // % means element-wise multiplication in Armadillo
  mat D = inv(X)*Y;
  int ee = trace(X.i()*Y) + log(det(X));

  // Create cube C with A and B as slices.
  cube C(A.n_rows, A.n_cols, 4);    
  mat E = zeros<mat>(A.n_rows, A.n_cols);
  E(0,0) = ee;
  C.slice(0) = A;
  C.slice(1) = B;
  C.slice(2) = D;
  C.slice(3) = E;   
  plhs[0] = armaCreateMxMatrix(C.n_rows, C.n_cols, C.n_slices);
  armaSetCubePr(plhs[0], C);
  return;

%%%%%%%错误%%%%%%%%%

我试过X，Y的尺寸是3*3， 4*4，没问题但是当我尝试使用 5*5 的矩阵求逆时，出现了失败 “分段错误（核心转储）”
