how to solve this problem?

I am getting this error continuously. I tried to change the input by adding and multiplying by a constant to the input but it is helping. can anyone please help me with this? I have attached all the required functions and code with the input cell array.

Error using svd
Input to SVD must not contain NaN or Inf.
Error in gplda_em
>calc_white_mat (line 135)
[~, D, V] = svd(X);
Error in gplda_em (line 58)
W1   = calc_white_mat(cov(data'));
Error in tes1 (line 37)
pLDA = gplda_em(finalDevIVs, speakerID(:), nphi, niter);

Excepting didn't show the error in context with what created it...

There appear to be non-finite (that is, NaN or Inf) values in your ‘data’ array. You have to find them and deal with them appropriately.
