Hi guys.
I'm new in Matlab and now I have a problem for the implementation of a simple speaker recognition system using PNCC and MFFC.
My problem is on matrix dimension in fact, when I run my program, it give me this error:
Matrix dimensions must agree.
Error in disteu (line 43)
d(n,:) = sum((x(:, n+copies) - y) .^2, 1);
Error in test (line 22)
d = disteu(v, code{l});
Error in main (line 4)
test('C:\Users\Antonio\Documents\MATLAB\test\',5, code);
Just for the sake of clarity I have attached my code.
Could anyone help me please?

Hi Antonio,
Here in the disteu file (line 43)
d(n,:) = sum((x(:, n+copies) - y) .^2, 1);
dimensions of x(:,n+copies) and y do not match, rows in x are 21+M whereas rows in y are 0+M2.
  • You may refer the padarray doc.
  • You may replace your code from line 21 to 34 in disteu file by this:
if (M < M2)
x = padarray(x,M2-M,0,'post');
[M, N] = size(x)
else
y = padarray(y,M-M2,0,'post');
[M2, P] = size(y)
end
