I am working on speech recognition.I have saved the coefficients of 4 audio files in a matrix in mat file. Now I want to compare those with a test audio file but I keep getting on this error Undefined function or method 'minus' for input arguments of type 'struct' . Can someone please guide me about how can I subtract the coefficients of tested audio sample from all the coefficients in mat file. code is below.
d=load ('Database.mat')
% line 1 loads the Database
[s1,fs] = wavread('x1.wav'); % Reading new file x1.wav
B = [1 -0.95];
s1 = filter(B,1,s1);%first order filter
[c]=melcepst(s1,fs);
n=corrcoef(c) ;% Finds the correlation coefficients
n=n(:); % writing all values in one column
n=abs(n);
dtw(1,1) = dist(1,1); % dynamic time wraping technique to see similarity between input signal and data base
dtw(d,n) = min (dtw(d-1, n-1), dtw(d-1, n), dtw(d, n-1)) + dist(d,n);

You can't use min like that, like min(num1,num2,num3). It only takes an array so enclose arguments in brackets: min([num1,num2,num3])
dtw(d,n) = min ([dtw(d-1, n-1), dtw(d-1, n), dtw(d, n-1)]) + dist(d,n);

We can run the debugger, if you can't do it, if you upload 'database.mat' and 'x1.wav'. I can't run your code without those two files of yours. You can speed things up if you think of these things in advance.
