Error :Unexpected matlab operator ????

i linked speech recognition code in matlab with vb.net so when i call it from vb this message appear

this is the code

 function test2 =test2()
clear;
[x,f]=audioread('C:\Users\TOSHIBA\father.wav');
extract=melcepst(x,f);
save( 'C:\Users\TOSHIBA\father.mat','extract');
[x1,f1]=audioread('C:\Users\TOSHIBA\color.wav');
extract2=melcepst(x1,f1);
save( 'C:\Users\TOSHIBA\color.mat','extract2');

Fid=fopen('C:\Users\TOSHIBA\path1.txt');
A=fscanf(Fid,'%u');
path=fscanf(Fid,'%s');
fclose=Fid;

[x,fsampling]=audioread(path);
pause(5);
x=fft(x);
fp=100;
fs=1000;
wp=2*fp/fsampling;
ws=2*fs/fsampling;
[N,wn]=buttord(wp,ws,1,5);
[b,a]=butter(N,wn);
y=filter(b,a,x);
soundsc((real(double(y))),fsampling)

[h,t]=impz(b,a);
N1=size(h,1);
n=1:N1;

extract=melcepst(y,fsampling);
if(A==1)
  B1=importdata('C:\Users\TOSHIBA\father.mat');
  d1=disteusq(extract,B1);
  result1=int64(sum(sum(d1)));
  if ((result1>=1517405)&&(result1<=3399480))
      test='true';
  else test='false';
  end
end
if(A==2)
  B2=importdata('C:\Users\TOSHIBA\color.mat');
  d2=disteusq(extract,B2);
  result2=int64(sum(sum(d2)));
  if ((result2>=521370)&&(result2<=668471))
      test='true';
  else test='false';
  end
end

so please what is the problem it can be :(

You have

function test2 =test2()

The variable that you assign to should never be the same as the name of the function itself. Your function calculates "test" so probably that is the variable name you want on the left side.

please anyone answer me :(

There is no unexpected operator in that code. Please show more about how you are invoking the code.

You can't do

fclose=Fid;

You need to do

fclose(Fid);
