You need to specify the matrix to be written onto the file: dlmwrite('H.txt', H) – Luis Mendo
Thanks Lui mendo, I've tried your code but I'm finding this error : Undefined function 'real' for input arguments of type 'struct'. Error in dlmwrite (line 189) str = sprintf('%.*g%+.*gi',precn,real(m(i,j)),precn,imag(m(i,j))); – m2016b
Sorry, I didn't realize H is a field of a struct variable called code. Try dlmwrite('H.txt', code.H) – Luis Mendo

dlmwrite is not recommended by matlab: Better use 

load('H.mat')
writematrix(H, 'H.txt')

see writematrix documentation.
