I have problem with my code.
??? Error using ==> horzcat CAT arguments dimensions are not consistent.
Error in ==> rozpoznawanie_dzwiekowPerc at 209 mfcc_kaszel = [mfcc_kaszel; [c sp_bw sp_centroid sp_rolloff shortte zerocr]];

Can you post your code? Make sure that each vector your are trying to concatenate has the same number of rows. Errors like this usually happen when you try to concatenate a row vector with a column vector.

I'm not sure if you want an 82 row by 18 column array as the output, or a 18 row by 82 column array, so here is how to do it both ways:
% Define sample data for testing.
mfcc_kaszel = [];
c = ones(82,13);
shortte = ones( 82,1);
sp_bw = ones( 1,82);
sp_centroid = ones(1,82);
sp_rolloff = ones( 1,82);
zerocr = ones(82,1);
% Make 82 row by 18 column matrix.
mfcc_kaszel = [mfcc_kaszel; [c, sp_bw', sp_centroid', sp_rolloff', shortte, zerocr]];
% Make 18 row by 82 column matrix.
mfcc_kaszel2 = [c'; sp_bw; sp_centroid; sp_rolloff; shortte'; zerocr'];

So I think you'd better track down why the sizes are not at all what you expect.

The problem is in
[mfcc_kaszel; [c sp_bw sp_centroid sp_rolloff shortte zerocr]]
[c sp_bw sp_centroid sp_rolloff shortte zerocr] is a 1x3 matrix. Unless mfcc_kaszel is nx3 matrix this operation in not allowed.
what is the dimension of mfcc_kaszel?

The problem is that the dimensions of sp_bw, sp_centroid and sp_rolloff are 1x82 while the same for c, shortte and zerocr are 82xn. mfcc_kaszel is a null vector so it doesn't matter.
I think you need to change the code like this:
mfcc_kaszel = [mfcc_kaszel; [c sp_bw' sp_centroid' sp_rolloff' shortte zerocr]];
which will work.
