Hi people I have this error entering a function: (really the error lines are more than this I put)

  *** glibc detected *** /home/elvio/workspace/aws/Debug/aws: double free or corruption    (!prev): 0x0000000001eff100 ***
  ======= Backtrace: =========
  /lib/x86_64-linux-gnu/libc.so.6(+0x7eb96)[0x7f950c739b96]

  /home/elvio/workspace/aws/Debug/aws(_ZNSt6vectorId

The function is : (I print Welcome to see in console I enter in the function)

   void pre_filter_Computations(vector< vector<double> > radius,vector< vector<double> > theta,int cols,int rows){

   vector<double>x(cols);
   vector<double>y(rows);
   vector< vector<double> >X(cols, vector<double>(rows));
   vector< vector<double> >Y(cols, vector<double>(rows));
   double epsilon = 0.0001;

   printf("welcome\n");

   for(int i=0;i<cols;i++){
   x[i]=((double)(i-cols)/2)/((double)cols/2);
   }

   for(int z=0;z<rows;z++){
   y[z]=-(((double)(z-rows)/2)/((double)rows/2));
   }

   for(int m=0;m<cols;m++){
      for(int n=0;n<rows;n++){

        X[m][n]=x[m];
        Y[m][n]=y[n];
     }
   }

   for(int a=0;a<rows;a++){
        for(int b=0;b<cols;b++){

             X[a][b] = pow(X[a][b],2);
             Y[a][b] = pow(Y[a][b],2);
             X[a][b] = X[a][b] + Y[a][b];
              radius[a][b] = sqrt(X[a][b]);

        }
    }

    radius[rows/2][cols/2]=1;

    for(int a=0;a<rows;a++){
       for(int b=0;b<cols;b++){
           radius [a][b]= radius[a][b] + epsilon;
           theta[a][b] = atan2(Y[a][b],X[a][b])*180/PI;
       }
    }
